Comparator
The block diagram of the comparator is shown in figure 60. The comparator compares input voltage with
the reference voltage.
Setting 1 to bit 3 (CER3) of the compare enable register (CER: $018) executes a voltage comparison.
When an input voltage at COMP
0
, COMP
1
is higher than the reference voltage, the TM or TMD command
sets the status flag (ST) high for the corresponding bits of the compare data register (CDR: $017) to
COMP
0
and COMP
1
. On the other hand, when an input voltage at COMP
0
, COMP
1
is lower, the TM or
TMD command clears the ST to 0.
