Bit 7 : AnalogBus Enable output to the analog bus
0 = Disable output to analog column bus
1 = Enable output to analog column bus
(The output on the analog column bus is affected by the state of the ClockPhase bit in Control 0 Register
(ASB11CR0, ASB13CR0, ASB20CR0, ASB22CR0). If AnalogBus is set to 0, the output to the analog column bus is
tri-stated. If AnalogBus is set to 1, the ClockPhase bit selects the signal that is output to the analog column bus. If the
ClockPhase bit is 0, the block output is gated by sampling clock on last part of PHI2. If the ClockPhase bit is 1, the
block output continuously drives the analog column bus)
Bit 6 : CompBus Enable output to the comparator bus
0 = Disable output to comparator bus
1 = Enable output to comparator bus
Bit 5 : AutoZero Bit for controlling gated switches
0 = Shorting switch is not active. Input cap branches shorted to op-amp input
1 = Shorting switch is enabled during internal PHI1. Input cap branches shorted to analog ground during internal
PHI1 and to op-amp input during internal PHI2.
