I want to know the usage of the RC5 of PIC16f877.I have been knowledge with the usage of RC6&RC7 in PIC16F877.These are always used in serial data access.

the rc 5 pin is used as a spi data output pin when in spi mode
or as a GP soft uart serial data output pin

this would be used along with rc 4 data input pin

appart from this it can be used as a general purpose {schmit triggered input }buffered
i/o pin

nothing special

most people use this pin sometimes to drive external eeprom etc...

to clock data into other chipset etc...

use it as you want if you dont use these modes

ive used it for buttons and switches also
