Answer code
(RWrn+2)
Set the monitor codes (refer to Section 3.5.3) to Monitor 1 (RWwn) and Monitor 2 (RWwn+1) and turn
Monitor output execution demand (RYn8) to ON. Turning Monitor execution demand (RYn8) to ON sets
the next data. 32-bit data are all divided into the upper 16 bits and lower 16 bits, and set to the remote
register. Data are all hexadecimal numbers. At this time, Monitoring (RXn8) turns to ON at the same
time.
Monitor data 1 under 16 bit (RWrn): Lower 16 bits of data demanded by Monitor 1 (RWwn)
Monitor data 1 upper 16 bit (RWrn+1): Upper 16 bits of data demanded by Monitor 1 (RWwn)
Monitor data 2 under 16 bit (RWrn+5): Lower 16 bits of data demanded by Monitor 2 (RWwn+1)
Monitor data 2 upper 16 bit (RWrn+6): Upper 16 bits of data demanded by Monitor 2 (RWwn+1)
A sign is set if data does not exist in RWrn+1 RWrn+6. A " " sign is indicated by "0000", and " " by
"FFFF".
The monitor data set to the remote register are always updated while Monitoring (RXn8) is ON.
When Monitoring (RXn8) turns to OFF, the data set to Monitor data RWrn, RWrn+1, RWrn+5, RWrn+6
are held.
If the monitor code not in the specifications is set to either Monitor 1 (RWwn) or Monitor 2 (RWwn+1), the
corresponding error code ( 1) is set to Answer code.
