8.14.3
PEPIN indicates the pin states of port E.
Note: The initial value of these pins is determined in accordance with the state of pins PE7 to
8.14.4
Port E also functions as an LPC input/output. The pin function is switched with LPC enabled or
disabled. The LPC module is disabled when the LPC1E, LPC2E, and LPC3E bits in HICR0 of
LPC are all 0.

Description
Pin states can be read by performing a read cycle on
this register.
This register is assigned to the same address as that
of PEDDR. When this register is written to, data is
written to PEDDR and the port E setting is then
changed.
