DESCRIPTION

Debug Port Bit Clock/Chip Status 1 (Input/Output)/General

Purpose I/O (Input/Output). The serial clock for the Debug Port is

provided when an input. When an output, together with OS0

provides information about the chip status. Optionally it can be

used as a general purpose I/O.

Debug Port Request Input (Input). Means of entering the Debug

mode of operation.

Supply pin dedicated to the digital periphery.

Ground pin dedicated to the digital periphery.

Analog Inputs (Input). Single ended analog signal inputs to the

ADC.

Analog Inputs (Input). Single ended analog signal inputs to the

ADC.

Analog Inputs (Input). Single ended analog signal inputs to the

ADC.

Analog Inputs (Input). Single ended analog signal inputs to the

ADC.

Voltage Reference (Input). External decoupling of the analog

reference used for the single to differential ended converter.

Voltage Reference (Input). Analog voltage reference input. Signal

is supplied by A354.

Voltage Reference (Input). External decoupling of the analog

references used for the sigma delta modulator.
