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 • 1024 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 0–767 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 |
