AINTEN
Bit 6
ADC Interrupt flag. This bit must be cleared with software.
0 = No interrupt request
1 = The AINTF flag is set when ADSF goes from '0' to '1.' Interrupts CPU when
both AINTF and AINTEN are set to '1.'
ADC Interrupt Enable
0 = ADC interrupt is disabled
1 = ADC interrupt is enabled
ADC Enable Bit
0 = ADC shut off and consumes no operating current
1 = Enable ADC. After ADC is enabled, 16ms of calibration is needed before
ADST Bit is set.
Analog channel Select
000 Select channel 0 (P1.0)
001 Select channel 0 (P1.1)
010 Select channel 0 (P1.2)
011 Select channel 0 (P1.3)
101 Select channel 0 (P1.5)
110 Select channel 0 (P1.6)
111 Select channel 0 (P1.7)
ADC Start Bit
0 = Force to zero
1 = Start ADC, then after one cycle, the bit is cleared to '0.'
ADC Status Bit
0 = ADC conversion is not completed
1 = ADC conversion is completed. The bit can also be cleared with software.
