(55) GPCR7
*1: Depends on the pin status.
This register (GPDC[7:0]) stores the input/output data of general-purpose input/output port C[7:0] (GPIOC[7:0]).
When it is set as a general-purpose output port, if a value is written to any bit of this register, the written value is
output from the corresponding pin. Also in this case, if any bit of this register is read, the value of the corresponding
bit is read.
When it is set as a general-purpose input port, if any bit of this register is read, the status of the corresponding pin can
be read. Also in this case, if a value is written to any bit of this register, the register value is updated but the status of
the pin does not change.
