19.2.5 Port C I/O Register L (PCIORL)
PCIORL is a 16-bit readable/writable register that is used to set the pins on port C as inputs or
outputs. Bits PC1IOR and PC0IOR correspond to pins PC1/A1 and PC0/A0, respectively.
PCIORL is enabled when the port C pins are functioning as general-purpose inputs/outputs (PC1
and PC0). In other states, PCIORL is disabled. A given pin on port C will be an output pin if the
corresponding bit in PCIORL is set to 1, and an input pin if the bit is cleared to 0.
Bits 15 to 2 of PCIORL are reserved. These bits are always read as 0. The write value should
always be 0.
PCIORL is initialized to H'0000 by a power-on reset; however, the register is not initialized by a
manual reset or in sleep mode or software standby mode.

19.2.6 Port C Control Register L1 (PCCRL1)
PCCRL1 is a 16-bit readable/writable register that is used to select the functions of the
multiplexed pins on port C.
PCCRL1 is initialized to the value shown in table 19.8 by a power-on reset; however, the register
is not initialized by a manual reset or in sleep mode or software standby mode.
