Description
Sample & Hold signal.
Sample analog signal
when low. Hold signal
when high. If differential
amplifier is used, this
signal must go active
when ACLK is high.
Enables Band-gap
reference as AREF
signal to DAC

signal, bit 0
Enable pass-gate of
differential amplifier.
Precharge output latch of
comparator. (Active low)
Switch-cap TEST enable.
Output from differential
amplifier is sent out to
Port Pin having ADC_4
Output of differential
amplifier will settle faster
if this signal is high first
two ACLK periods after
AMPEN goes high.
Selects Vcc as the ACC
reference voltage.
