18. I/O Ports
18.5.2
The port E data register L (PEDRL) is a 16-bit readable/writable registers that stores port E data.
Bits PE15DR to PE0DR correspond to pins PE15 to PE0 (multiplexed functions omitted here).
When a pin functions is a general output, if a value is written to PEDRL, that value is output
directly from the pin, and if PEDRL is read, the register value is returned directly regardless of the
pin state.
When a pin functions is a general input, if PEDRL is read, the pin state, not the register value, is
returned directly. If a value is written to PEDRL, although that value is written into PEDRL it
does not affect the pin state. Table 18.5 summarizes port E data register read/write operations.
