Figure 17. Data Indirect Addressing with Pre-decrement
The X, Y or Z register is decremented before the operation. Operand address is the
decremented contents of the X, Y or Z register.
Figure 18. Data Indirect Addressing with Post-increment
The X, Y or Z register is incremented after the operation. Operand address is the con-
tent of the X, Y or Z register prior to incrementing.
Figure 19. Code Memory Constant Addressing
Constant byte address is specified by the Z register contents. The 10 MSBs select word
