When the respective bits are written to
logic one, the digital input buffer on the corresponding ADC pin is disabled. The
corresponding PIN Register bit will always read as zero when this bit is set. When an
analog signal is applied to the ADC[7:0] pin and the digital input from this pin is not
needed, this bit should be written logic one to reduce power consumption in the digital
input buffer.
ADC3 Digital Input
Disable
Not apply for
AC.
ADC2 Digital Input
Disable
Not apply for
AC.
ADC1 Digital Input
Disable
When this bit is
written logic one, the digital input buffer on the corresponding ADC pin is
disabled. The corresponding PIN register bit will always read as zero when this bit
is set. When an analog signal is applied to the ADC[7:0] pin and the digital input
from this pin is not needed, this bit should be written logic one to reduce power
consumption in the digital input buffer.
ADC0 Digital Input
Disable
When this bit is
written logic one, the digital input buffer on the corresponding ADC pin is
disabled. The corresponding PIN register bit will always read as zero when this
bit is set. When an analog signal is applied to the ADC[7:0] pin and the digital
input from this pin is not needed, this bit should be written logic one to
reduce power consumption in the digital input buffer.
