Description
I/O Debug Port Serial Input/Chip Status 0 (Input/Output)/ General
Purpose I/O (Input/Output). The serial data input for the Debug
Port is provided when an input. When an output, together with
OS1 provides information about the chip status. Optionally it can
be used as a general purpose I/O.
I/O 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.
I Debug Port Request Input (Input). Means of entering the Debug
mode of operation.
Supply pin dedicated to the digital circuitry.
Ground pin dedicated to the digital circuitry.
I Analog Inputs (Input). Single ended analog signal inputs to the
ADC.
