Section 27 Pin Function Controller (PFC)
27.2.19 Port K I/O Register L (PKIORL)
PKIORL is 16-bit readable/writable register that is used to set the pins on port K as inputs or
outputs. The PK11IOR to PK0IOR bits correspond to the PK11 to PK0 pins respectively. The
setting of PKIORL is valid for the pins for which general I/O function is selected and has no effect
on the pins for which other function is selected. If a bit in PKIORL is set to 1, the corresponding
pin on port K functions as an output pin. If it is cleared to 0, the corresponding pin functions as an
input pin.
Bits 15 to 2 in PKIORL are reserved. These bits are always read as 0. The write value should
always be 0.

27.2.20 Port K Control Register L1 (PKCRL1)
PKCRL1 is 16-bit readable/writable register that is used to select the functions of the multiplexed
pins on port K. See table 27.10 for the multiplexed functions.
