12.4 UT35A-L D Registers
Process Data Area
Some of the D registers represent multiple events such as errors and status depending
on combinations of bits in the register.
In the following tables, if an event indicated by a specific bit occurs, the state of that bit
changes to “1.”
If no event occurs, the state of that bit is “0.” Blank lines in each table indicate unused
bits.
