Description

The PIC16F887-I/P is one member of the PIC16F887 series.It has the following features including Timer0:8-bit timer/counter with 8-bit programmable prescaler;Timer2:8-bit timer/counter with 8-bit period register,prescaler and postscaler;Enhanced low-current Watchdog Timer(WDT) with on-chip oscillator(software selectable nominal 268 seconds with full prescaler)with software enable;Multiplexed Master Clear with pull-up/input pin;Programmable code protection;Power-Saving Sleep mode;Wide operating voltage range(2.0V-5.5V);Industrial and Extended Temperature range.

The PIC16F887-I/P devices have an 8-level x 13-bit wide hardware stack(see Figures 2-2 and 2-3).The stack space is not part of either program or data space and the Stack Pointer is not readable or writable.The PC is PUSHed onto the stack when a CALL instruction is executed or an interrupt causes a branch.The stack is POPed in the event of a RETURN,RETLW or a RETFIE instruction execution.PCLATH is not affected by a PUSH or POP operation.About the PIC16F887-I/P, The stack operates as a circular buffer.This means that after the stack has been PUSHed eight times,the ninth push overwrites the value that was stored from the first push.The tenth push overwrites the second push(and so on).

A computed GOTO is accomplished by adding an offse to the program counter(ADDWF PCL).Care should be exercised when jumping into a look-up table o program branch table(computed GOTO)by modifying the PCL register.Assuming that PCLATH is set to the table start address,if the table length is greater than 255 instructions or if the lower 8 bits of the memory address rolls over from 0xFF to 0x00 in the middle the table,then PCLATH must be incremented for each address rollover that occurs between the table beginning and the target location within the table.Use of Microchip's products PIC16F887-I/P as critical components in life support systems is not authorized except with express written approval by Microchip.
