7.2.2
PORT C SIGNALS AND REGISTERS
Each of the 12 port C signals not used as an ESAI signal can be configured individually as a
GPIO signal. The GPIO functionality of port C is controlled by three registers: port C control
register (PCRC), port C direction register (PRRC), and port C data register (PDRC). These
registers are described in Section 10 - Enhanced Serial Audio Interface (ESAI).
7.2.3
PORT D SIGNALS AND REGISTERS
Each of the two Port D signals not used as a DAX signal can be configured individually as a
GPIO signal. The GPIO functionality of Port D is controlled by three registers: Port D control
register (PCRD), Port D direction register (PRRD) and Port D data register (PDRD). These
registers are described in Section 12 - Digital Audio Transmitter.
7.2.4
PORT E SIGNALS AND REGISTERS
Port E has 10 signals, shared with the ESAI_1. Six of the ESAI_1 signals have their own pin,
so each of the six signals, if not used as an ESAI_1 signal, can be configured individually as a
GPIO signal. The other four ESAI_1 signals share pins with the ESAI. For these shared pins,
if the pin is not being used by the ESAI, Port C and the ESAI_1, then it may be used as a Port
E GPIO signal. The GPIO functionality of port E is controlled by three registers: port E
control register (PCRE), port E direction register (PRRE), and port E data register (PDRE).
These registers are described in Section 11 - Enhanced Serial Audio Interface 1 (ESAI_1).
7.2.5
TIMER/EVENT COUNTER SIGNALS
The timer/event counter signal (TIO), when not used as a timer signal can be configured as a
GPIO signal. The signal is controlled by the appropriate timer control status register (TCSR).
The register is described in Section 13 - Timer/ Event Counter.
