Enhanced Synchronous Serial Interface (ESSI)
GPIO Signals and Registers
RESET signal or a software RESET instruction clears all PCR bits.
PCR bits

7.6.2
Port Direction Register (PRR)
The read/write, 24-bit PRR controls the data direction of the ESSI GPIO signals. When
PRR[i] is set, the corresponding signal is an output signal. When PRR[i] is cleared, the
corresponding signal is an input signal.
