Section 17 Pin Function Controller (PFC)
PC0/A0. PCIORL is enabled when port C pins function as general input/output pins (PC15 to
PC0) or TPU TIOC pins, and disabled otherwise.
When port C pins function as PC15 to PC0 or TPU TIOC pins, a pin becomes an output when the
corresponding bit in PCIORL is set to 1, and an input when the bit is cleared to 0.
PCIORL is initialized to H'0000 by an external power-on reset, but is not initialized by a WDT
reset, in standby mode, or in sleep mode.
17.3.11 Port C Control Registers H1 and H2 (PCCRH1, PCCRH2)
Port C control registers H1 and H2 (PCCRH1, PCCRH2) are 16-bit readable/writable registers that
select the functions of pins in port C.
PCCRH1 selects the functions of port C pins PC25/A25/TIOC3B/TCLKD and
PC24/A24/TIOC3A/TCLKC, and PCCRH2 selects the functions of port C pins
PC23/A23/TIOC1B/TCLKB to PC16/A16/TIOC3A.
Port C includes address outputs (A16 to A25), but register settings relating to the selection of these
pin functions may not be valid in all operating modes. For details, see table 17.10, Pin Functions
in Each Operating Mode.
PCCRH1 and PCCRH2 are initialized to H'0000 by an external power-on reset, but are not
initialized by a WDT reset, in standby mode, or in sleep mode.
