0). At
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 chan-
nel. There are a total of four 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 converter circuit is
power on. The EOC bit (bit6 of the ADCR) is
end of A/D conversion flag. Check this bit to
know when A/D conversion is completed. The
START bit of the ADCR is used to begin the
conversion of A/D converter. Give START bit a
raising edge and falling edge that means the
A/D conversion has started. In order to ensure
the A/D conversion is completed, the START
should stay at 0 until the EOC is cleared to
0 (end of A/D conversion).
The bit 7 of the ACSR is used for testing pur-
pose only. It can not be used for the users. The
bit1 and bit0 of the ACSR are used to select A/D
clock sources.
