Legend: y = POR value is determined by the specific device
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 31-0 AN<31:0>: ADC Analog Input bits
These bits reflect the system configuration and are updated during boot-up time. By reading these read-
only bits, the user application can determine whether or not an analog input in the device is available.
AN<31:0>: Reflects the presence or absence of the respective analog input (AN31-AN0).

These bits reflect the system configuration and are updated during boot-up time. By reading these read-
only bits, the user application can determine whether or not an analog input in the device is available.
AN<63:32>: Reflects the presence or absence of the respective analog input (AN63-AN32).
