The upper nibble of the register pointer (see
group, of 16 bytes in the register file, is accessed out of the possible 256. The lower nibble
selects the expanded register file bank and, in the case of the Crimzon ZLP32300 family,
banks 0, F, and D are implemented. A
file (bank 0) to be addressed. Any other value from
registers to an expanded register bank.
Example: Crimzon ZLP32300 (see
R253 RP = 00h
R0 = Port 0
R1 = Port 1
R2 = Port 2
R3 = Port 3
But if:
R253 RP = 0Dh
R0 = CTR0
R1 = CTR1
R2 = CTR2
R3 = CTR3
The counter/timers are mapped into ERF group D. Access is easily performed using the
following:
