Instruction Set
Details concerning the PCF5083 Instruction Set can be found in the “PCF5082 Information manual” Some exceptions
that apply to the PCF5083 are listed below:
Moves from RAM using pointers to I/O control registers (iopc, iopcx and sioc) are not recommended due to reliability
problems. Load immediate from program memory to these registers should be performed. Otherwise, access to the
I/O control registers could be performed via secondary registers e.g.
bm = *px0++ followed by sioc = bm
All code segments using pp pointer as source must be within a disable/enable pair if interrupts are enabled e.g. disable;
.....
bm = *pp++;
.....
The instruction *px0++ is illegal. Instead, use the following sequence with consideration to the point above:
dr = *pp++;
*px0++ = dr;
The instruction ‘.... = *pp++’ may be located in any PROM bank (including the mirrored PROM07 at location
XF800H to XFFFF0. However, the instruction will not work if located in any of the RAM banks mapped to program
address space.
