32.2.32 Port J Data Register 0 (PJDR0)
PJDR0 is a 16-bit readable/writable register that stores port J data. The PJ11DR to PJ0DR bits
correspond to the PJ11 to PJ0 pins, respectively.
When a pin function is general output, if a value is written to PJDR0, that value is output from the
pin, and if PJDR0 is read, the register value is returned directly regardless of the pin state.
When a pin function is general input, if PJDR0 is read, the pin state, not the register value, is
returned directly. If a value is written to PJDR0, although that value is written into PJDR0, it does
not affect the pin state. Table 32.20 summarizes PJDR0 read/write operation.
