33.5 Pin Name List
33.6 Product Dependencies
33.6.1 I/O Lines
The pins used for interfacing the compliant external devices may be multiplexed with PIO lines.
Before using the SSC receiver, the PIO controller must be configured to dedicate the SSC receiver I/O lines to the
SSC peripheral mode.
Before using the SSC transmitter, the PIO controller must be configured to dedicate the SSC transmitter I/O lines
to the SSC peripheral mode.
33.6.2 Power Management
The SSC is not continuously clocked. The SSC interface may be clocked through the Power Management
Controller (PMC), therefore the programmer must first configure the PMC to enable the SSC clock.
