6.3 Addressing
The P8xCE559 has five methods 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 register banks through Register, Direct
or Register–Indirect addressing
• 1536 bytes of internal RAM through Direct or Register–Indirect
addressing. Bytes 0–127 of internal RAM may be addressed
directly/indirectly. Bytes 128–255 of internal RAM share their
address location with the SFRs and so may only be addressed
indirectly as data RAM. Bytes 0–1279 of AUX–RAM can only be
addressed indirectly via MOVX.
• Special Function Register through direct addressing at address
locations 128–255 (see Figure 8).
• External data memory through Register–Indirect addressing
• Program memory look–up tables through Base– Register plus
Index–Register–Indirect addressing
