Addressing
The P89C738 has five modes for addressing:
Register
Direct
Register-Indirect
Immediate
Base-Register plus Index-Register-Indirect.
The first three methods can be used for addressing
destination operands. Most instructions have a
‘destination/source’ field that specifies the data type,
addressing methods and operands involved.
For operations other than MOVs, the destination operand
is also a source operand.
Access to memory addresses is as follows:
Register in one of the four 8-bit register banks through
Register, Direct or Register-Indirect addressing
512 bytes of internal RAM through Direct or
Register-Indirect addressing. Bytes 0 to 127 of internal
RAM may be addressed directly/indirectly. Bytes
128 to 255 of internal RAM share their address location
with the SFRs and so may only be addressed indirectly
as data RAM. Bytes 0 to 255 of AUX-RAM can only be
addressed indirectly via MOVX.
SFR through Direct addressing at address locations
128 to 255
External data memory through Register-Indirect
addressing
Program memory look-up tables through Base-Register
plus Index-Register-Indirect addressing.
