15.4.4 Operation of VER (Continuous Monitor)

When the VER (continuous monitor) command is issued, the RTD outputs the data from the address that has

been accessed by an instruction (either read or write) immediately before receiving the VER command.

15.4.5 Operation of VEI (Interrupt Request)

When the VEI (interrupt request) command is issued, the RTD generates an interrupt request. Furthermore, the

RTD outputs the data from the address that has been accessed by an instruction (either read or write) immediately

before receiving the VEI command.
