Chapter 5 Applied Instructions 5.4 Using Index Registers to Modify Operands V devices are 16-bit index registers. There are 6 V devices (V0~V5). Z devices are 32-bit index registers. There are 8 Z devices (Z0~Z7). 16 bits V0~V7 V devices are 16-bit registers. Data can be freely written into a V device, and data can be freely read from a V device. If a 32-bit value is required, please use a Z device. 32 bits Z0~Z7 High byte Low byte Index registers can be used to modify X/Y/M/S/KnM/KnS/T/C/D/SM/SR devices, but they can not be used to modify index registers, constants, and Kn. For example, K4@Z0 is invalid, K4M0@Z0 is valid, and K0@Z0M0 is invalid.
The devices marked with “●” in the table in the explanation of an applied instruction can be modified by V devices and Z devices.
