Figure 15. Data Indirect Addressing with Pre-decrement
The X-, Y-, or the Z-register is decremented before the operation. Operand address is
the decremented contents of the X-, Y-, or the Z-register.
Figure 16. Data Indirect Addressing with Post-increment
The X-, Y-, or the Z-register is incremented after the operation. Operand address is the
content of the X-, Y-, or the Z-register prior to incrementing.
Figure 17. Code Memory Constant Addressing
Constant byte address is specified by the Z-register contents. The 15 MSBs select word
address (0 - 4K), the LSB selects low byte if cleared (LSB = 0) or high byte if set (LSB =
1).
