When the switch S7 is on by setting this bit high, the operational amplifier n output
signal will be internally connected to the comparator n positive input. Therefore the
CMPnP pin function should be first switched off by properly configuring the relevant
pin-shared control bits to avoid signal confliction.

Bit 7
OPnOUT
: OCP Operational Amplifier n digital output bit, positive logic (read only)
When the OCP Operational Amplifier n is disabled, this bit will be cleared to zero.
When the OnOFM bit is set high, the OPnOUT bit is defined as OCP Operational
Amplifier n output status, refer to the “Operational Amplifier Input Offset Calibration”
section for the detailed offset calibration procedures.
Bit 6
OPnEN
: OCP Operational Amplifier n enable or disable control bit
0: Disable
1: Enable
Bit 5~2
Unimplemented, read as “0”

Bit 7
OnOFM
: OCP Operational Amplifier n operating mode selection
0: Normal operating mode
1: Input offset calibration mode
This bit is used to select the OCP Operational Amplifier n
operating mode
. If the bit
is zero the OCP Operational Amplifier n will operate normally. The OCP Operational
Amplifier n will enter the offset calibration mode if this bit is set high. Refer to
the “Operational Amplifier Input Offset Calibration” section for the detailed offset
c
alibration procedures.
Bit 6
OnRSP
: OCP Operational Amplifier n input offset voltage calibration reference
selection
0: From OPAnN pin
1: From OPAnP pin
This bit is used to select the OCP Operational Amplifier n input offset calibration
reference. When the OCP Operational Amplifier n is in the offset calibration mode,
the calibration reference input can come from the OCP Operational Amplifier n inputs,
OPAnN or OPAnP, determined by this bit. This bit is only available when the OCP
Operational Amplifier n operates in offset calibration mode.
