See Interrupt Sources Firmware Instructions In 16f877 datasheet Counter mode, the compare operation may not work.

The reference voltage VREF has no effect on the equation, since it cancels itself out.

The write initiate sequence, and the WREN bit together, help prevent any accidental writes during brown-out, power glitches, or firmware malfunction. This bit 16f877 datasheet be cleared by firmware.

PIC16F877A Microcontroller

On a Power-on Reset, these pins are configured as 16f877 datasheet inputs and read as ‘0’. All other trademarks mentioned herein are property of their respective companies. The Microchip logo and name are registered trademarks of Microchip Technology Inc.

After this 2TAD wait, acquisition on the selected channel is automatically started. Bus collision occurs during a STOP condition if: No licenses are conveyed, implicitly or otherwise, under any intellectual property rights.

The user must provide a software datashedt delay to 16f877 datasheet proper oscillator start-up. An on-chip, dedicated, 8-bit baud rate generator can be 16f877 datasheet to derive standard baud rate frequencies from the oscillator.

Also, the prescaler counter will not be cleared, therefore, the first capture may be from a non-zero prescaler. The high and low times of 16f877 datasheet I2C specification, as well as the requirement of the 16f877 datasheet module, 16f877 datasheet shown in timing parameter and parameter of the electrical specifications. All implemented banks contain Special Function Registers. Back-to-back transfers are possible.

Timer2 is an 8-bit timer with a prescaler and a postscaler. VDD as a function of Rp is shown in Figure When the write completes, the next instruction in the pipeline is executed 16f877 datasheet the branch to the interrupt vector will take place, if the interrupt is enabled and occurred during the write. Those related to the operation of the peripheral features are described in detail in the peripheral features section.

The low byte comes from the PCL register, which is a readable and writable register. This filter operates in both the kHz and kHz modes.

When code protection is enabled and CPD cleared, external access via ICSP is disabled, regardless of the state of the program memory code protect bits. The heart of the transmitter is the transmit serial shift register TSR. Unused in this mode bit 1 TRMT: The MPLAB ICE in-circuit emulator system has been designed as a real-time emulation system, with advanced features that are generally found on more expensive 16f877 datasheet tools.

Information contained in this publication 16f877 datasheet device applications and the like is 16f877 datasheet through suggestion only and may be superseded by updates. If MCLR is kept low long enough, the time-outs datashdet expire.

A back-to-back transfer is thus possible Figure If RSEN is programmed while any other event is in progress, it will not take effect. A typical transmit sequence would go as follows: Since the microcontroller does not execute instructions during the write cycle, the firmware does not necessarily have to check either EEIF, or WR, 16f877 datasheet determine if the write had finished.

The baud rate generator is then reloaded and counts down to 0. It should 16f877 datasheet noted, 16f877 datasheet once 16f877 datasheet LVP bit is programmed to 0, only the High Voltage Programming mode is available and only High Voltage Programming mode can be used to program the device.

If 9-bit transmission is desired, then set transmit bit 16f877 datasheet. In the kHz mode, when these pins are an output, there is 16f877 datasheet slew rate control of the pin that is independent of device frequency. To accomplish communication, typically three pins are used: Read as ‘0’ bit PCFG3: Once write protection is enabled, only an erase of the entire device will disable it.

RD0 62 64 63 Note: 16f877 datasheet the interrupt is serviced, the source for the interrupt can be checked by reading the contents of the SSPBUF to determine if the address was device specific, or a general call address. Indirect addressing is possible by using the INDF register. The general call address is one of eight addresses reserved for specific purposes by the I2C protocol.

A write operation causes 16f877 datasheet erase-then-write operation to take place on the specified byte or word. The upper byte of the program counter is not directly accessible. Therefore, one master will always assert SDA before the other. Interchangeable processor modules allow the system to be easily reconfigured for emulation of different processors.

An ACK pulse is generated. In I2 C Master mode: Data should be valid before SCL is released high see data setup time spec.

Shaded cells datasheeet not 16f877 datasheet by 16f877 datasheet and Timer1. The 8-bit timer is concatenated with 2-bit internal Q clock, datashet 2 bits of the prescaler, to create bit timebase. In addition to this, the oscillator frequency will vary from unit to unit due to normal process parameter variation. See notes following this table.

In Slave mode, the data is transmitted and received as the external clock pulses appear on SCK. If step 10 is not implemented, check the WR bit to see if a 16f877 datasheet is in progress.
