14.3.4 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.
RTDRXD
Notes: • X = Don't care.
(However, if issued immediately after the RCV command, bits 20-31 must all be set to 1.)

14.3.5 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.
RTDRXD
Note: • X = Don't care.
