ABL electronic PIC Microcontrollers PIC16 - Manual (Page 245)

mikroC provides a library for communicating with common PS/2 keyboard.The
library does not utilize interrupts for data retrieval, and requires oscillator clock to
be 6MHz and above.

PS/2 Library
Library Routines
Prototype void Ps2_Init(unsigned short *port);
Description Initializes
port
for work with PS/2 keyboard, with default pin settings. Port pin 0 is
Data line, and port pin 1 is Clock line.
You need to call either
Ps2_Init
or
Ps2_Config
before using other routines of PS/2
library.
Requires Both Data and Clock lines need to be in pull-up mode.
Ps2_Init
Prototype void Ps2_Config(char *port, char clock, char data);
Description Initializes
port
for work with PS/2 keyboard, with custom pin settings. Parameters
data
and
clock
specify pins of
port
for Data line and Clock line, respectively.
Data
and
clock
need to be in range 0..7 and cannot point to the same pin.
You need to call either
Ps2_Init
or
Ps2_Config
before using other routines of PS/2
library.
Requires Both Data and Clock lines need to be in pull-up mode.
Example Ps2_Config(&PORTB, 2, 3);
