PEPRL is a 16-bit read-only register that always returns the states of the pins regardless of the
PFC setting. Bits PE15PR to PE0PR correspond to pins PE15 to PE0 (multiplexed functions
omitted here) in the SH7125. Bits PE15PR to PE8PR and PE3PR to PE0PR correspond to pins
PE15 to PE8 and PE3 to PE0, respectively (multiplexed functions omitted here) in the SH7124.
