For bits 5–0, the value represents the level that is written to or read from the associated signal line if it is
enabled as a GPIO signal by the respective port control register (PCRC or PCRD) bits. For ESSI0, the GPIO
signals are PC[5–0]. For ESSI1, the GPIO signals are PD[5–0]. The corresponding data bits for Port C
GPIOs are PDRC[5–0]. The corresponding data bits for Port D GPIOs are PDRD[5–0].
