Enhanced Synchronous Serial Interface (ESSI)
7.6.2 Port Direction Registers (PRRC and PRRD)
The read/write PRRC and PRRD control the data direction of the ESSI0 and ESSI1 GPIO signals
when they are enabled by the associated Port Control Register (PCRC or PCRD, respectively).
When PRRC[i] or PRRD[i] is set, the corresponding signal is an output (GPO) signal. When
PRRC[i] or PRRD[i] is cleared, the corresponding signal is an input (GPI) signal. Either a
hardware
Table 7-6 summarizes the ESSI port signal configurations.
7.6.3 Port Data Registers (PDRC and PDRD)
Bits 5–0 of the read/write PDRs write data to or read data from the associated ESSI GPIO signal
lines if they are configured as GPIO signals. If a port signal PC[i] or PD[i] is configured as an
input (GPI), the corresponding PDRC[i] pr PDRD[i] bit reflects the value present on the input

PCRC/PCRD[i]
For Px[5–0], a 0 selects Pxn as the signal and a 1 selects the specified ESSI signal. For ESSI0, the GPIO signals are
PC[5–0] and the ESSI signals are STD0, SRD0, SCK0, and SC0[2–0]. For ESSI1, the GPIO signals are PD[5–0] and
the ESSI signals are STD1, SRD1, SCK1, and SC1[2–0].
For bits 5–0, a 0 configures PRxn as a GPI and a 1 configures PRxn as a GPO. For ESSI0, the GPIO signals are
PC[5–0]. For ESSI1, the GPIO signals are PD[5–0]. The corresponding direction bits for Port C GPIOs are PRC[5–0].
The corresponding direction bits for Port D GPIOs are PRD[5–0].
