Port C (PC0-PC7)
or output. The control register PCCR is used to set the port for input or output. A reset clears PCCR to 0,
putting port C in input mode. In addition to functioning as an input/output port, the pins of this port can
also function as various input/output pins: PC0, PC1 and PC2 function as 8-bit timer input or external
interrupt input, PC3 and PC5 as 8-bit timer output, PC6 as 16-bit timer input or key input, PC4 as 8-bit
timer input, and PC7 as 16-bit timer input or 8-bit timer output. These functions are enabled by setting the
corresponding bits of PCFC to 1.
enabled only when KWUPCNT<PE> is set to 1 in the key on wake-up circuit and key input is enabled in
KWUPSTn. For details, refer to the description of the key on wake-up function. When the pin is
functioning as a port pin, its pull-up resistor is disabled.
DVCC52. It becomes a VCC-based (3 V) port when VCC is supplied to DVCC52.
Port C is an 8-bit general-purpose input/output port whose bits can each be set independently for input
A reset clears PCCR and PCFC to 0, placing port C in input mode. PC6 has a pull-up resistor, which is
Port C becomes a 5 V input/output port when 5 V is supplied to its dedicated power supply pin
