INSTRUCTION SET
Since the I
2
C-bus interface, Port 2 and derivative logic are
not provided, instructions associated with these functions
are not available.
ROM space is restricted to 1 kbyte for the PCF84C12A,
2 kbytes for the PCF84C22A and 4 kbytes for the
PCF84C42A. Therefore, the instructions SEL MB1/2/3 for
the PCF84C12A and PCF84C22A, and the instructions
SEL MB2/3 for PCF84C42A should be avoided as they
would define non-existing program memory banks.
As RAM space is limited to 64 bytes, care should be taken
to avoid accesses to non-existing RAM locations.
Refer to the “PCF84CxxxA family” data sheet, for a
complete description of the instruction set.
