End of conversion flag (read only).
0 = A/D conversion in process
1 = End of A/D conversion
A/D converter prescaler enable.
0 = Disable
1 = Enable
A/D converter prescaler value.
Data value: 1 ~ 255
Note that division factor is (N+1) when the prescaler value is N.
NOTE: ADC frequency should be set less than PCLK by 5 times.
(Ex. PCLK = 10MHz, ADC Frequency < 2MHz)
Analog input channel select.
000 = AIN 0
001 = AIN 1
010 = AIN 2
011 = AIN 3
100 = AIN 4
101 = AIN 5
110 = AIN 6
111 = AIN 7 (XP)
Standby mode select.
0 = Normal operation mode
1 = Standby mode
A/D conversion start by read.
0 = Disable start by read operation
1 = Enable start by read operation
A/D conversion starts by setting this bit.
If READ_START is enabled, this value is not valid.
0 = No operation
1 = A/D conversion starts and this bit is cleared after the start-up.
