Data held
Set monitor codes to Monitor 1 (RWw0) and Monitor 2 (RWw1), and turn on Monitor output execution
demand (RY8). Turning on RY8 sets the following data. Data are all in hexadecimal. At this time,
Monitoring (RXC) turns on simultaneously.
Monitor data 1 (RWr0): Data demanded by Monitor 1 (RWw0)
Monitor data 2 (RWr1): Data demanded by Monitor 2 (RWw1)
For 32-bit data, set the under 16 bits of the monitor code to Monitor 1 (RWw0) and the upper 16 bits to
Monitor 2 (RWw1), and read them simultaneously.
The monitor data set to the registers are continuously updated while RX8 is on. When RX8 turns off, the
data set to Monitor data RWr0, RWr1 are held.
If the monitor code set to either or both of Monitor 1 (RWw0) and Monitor 2 (RWw1) does not exist in the
specifications, an error code (
1) is set to Answer code.
