Analog Switch Cap Type B Block xx Control 1 Register
AMux controls the input muxing for the A capacitor
branch.
The BCap bits set the value of the capacitor in the B
path.
Analog Switch Cap Type B Block 11 Control 1 Register (ASB11CR1, Address = Bank 0/1, 85h)
Analog Switch Cap Type B Block 13 Control 1 Register (ASB13CR1, Address = Bank 0/1, 8Dh)
Analog Switch Cap Type B Block 20 Control 1 Register (ASB20CR1, Address = Bank 0/1, 91h)
Analog Switch Cap Type B Block 22 Control 1 Register (ASB22CR1, Address = Bank 0/1, 99h)
