8.8 A-D COMPARATOR
The A-D comparator consists of a 7-bit D-A converter and a com-
parator. The A-D comparator block diagram is shown in Figure 8.8.1.
The reference voltage “V
ref
” for D-A conversion is set by bits 0 to 6 of
A-D control register 2 (address 00ED
16
).
The comparison result of the analog input voltage and the reference
voltage “V
ref
” is stored in bit 4 of A-D control register 1 (address
00EC
16
).
For A-D comparison, set “0” to corresponding bits of the direction
register to use ports as analog input pins. Write the data to select
analog input pins for bits 0 to 2 of A-D control register 1 and write the
digital value corresponding to V
ref
to be compared to bits 0
to 4 of A-D control register 2. The voltage comparison is started by
writing to A-D control register 2, and it is completed after 16 machine
cycles (NOP instruction
8).
