8.8 A-D COMPARATOR
A-D comparator consists of 6-bit D-A converter and comparator. 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 5 of
the A-D control register (address 00EF
16
).
The comparison result of the analog input voltage and the reference
voltage “V
ref
” is stored in bit 4 of the A-D mode register (address
00EE
16
).
For A-D comparison, set “0” to corresponding bits of the direction
register to use ports as analog input pins. Write the data for select of
analog input pins to bits 0 to 2 of the A-D control register 1 and write
the digital value corresponding to V
ref
to be compared to the bits 0
to 5 of the A-D control register. The voltage comparison starts by
writing to the A-D control register 2, and it is completed after 16 ma-
chine cycles (NOP instruction
8).
