A/D converter
The 8 channels and 10-bit resolution A/D (9-bit accu-
racy) converter are implemented in this microcontroller.
The reference voltage is VDD. The A/D converter con-
tains 4 special registers which are; ADRL (24H), ADRH
(25H), ADCR (26H) and ACSR (27H). The ADRH and
ADRL are A/D result register higher-order byte and
lower-order byte and are read-only. After the A/D con-
version is completed, the ADRH and ADRL should be
read to get the conversion result data. The ADCR is an
A/D converter control register, which defines the A/D
channel number, analog channel select, start A/D con-
version control bit and the end of A/D conversion flag. If
the users want to start an A/D conversion. Define PB
configuration, select the converted analog channel, and
give START bit a raising edge and falling edge

The A/D converter control register is used to control the
A/D converter. The bit2~bit0 of the ADCR are used to
select an analog input channel. There are a total of eight
channels to select. The bit5~bit3 of the ADCR are used
to set PB configurations. PB can be an analog input or
as digital I/O line decided by these 3 bits. Once a PB line
is selected as an analog input, the I/O functions and
pull-high resistor of this I/O line are disabled and the A/D
