A-D COMPARATOR
Block diagram of A-D comparator is shown in Figure 18. A-D com-
parator consists of 5-bit D-A converter and comparator. The A-D con-
trol register can generate 1/64 VCC-step internal analog voltage
based on the settings of bits 0 to 4.
Table 3 gives the relation between the descriptions of A-D control
register bits 0 to 4 and the generated internal analog voltage. The
comparison result of the analog input voltage and the internal analog
voltage is stored in the A-D control register, bit 5.
After selection of an analog input pin by bits 0-2 of A-D mode register
(address 00EE16), the digital value corresponding to the internal ana-
log voltage to be compared is then written in the A-D control register,
bit 0 to 3 and an analog input pin is selected. After 16 machine cycle,
the voltage comparison is completed.
