5.5.2 Port C Signals and Registers
Each of the six Port C signals not used as an ESSI0 signal can be configured as a GPIO signal.
Three registers control the GPIO functionality of Port C: Port C control register (PCRC), Port C
direction register (PRRC), and Port C data register (PDRC). Chapter 7, Enhanced Synchronous
Serial Interface (ESSI), discusses these registers.
5.5.3 Port D Signals and Registers
Each of the six Port D signals not used as an ESSI1 signal can be configured as a GPIO signal.
Three registers control the GPIO functionality of Port D: Port D control register (PCRD), Port D
direction register (PRRD), and Port D data register (PDRD). Chapter 7, Enhanced Synchronous
Serial Interface (ESSI), discusses these registers.
5.5.4 Port E Signals and Registers
Each of the three Port E signals not used as an SCI signal can be configured as a GPIO signal.
Three registers control the GPIO functionality of Port E: Port E control register (PCRE), Port E
