W
Setting a PCR6 bit to 1 makes the corresponding pin an
W
output pin, while clearing the bit to 0 makes the pin an
input pin. The settings in PCR6 and in PDR6 are valid
W
only when the corresponding pin is designated by the
W
SGS3 to SGS0 bits in LPCR as a general I/O pin.
W
PCR6 is a write-only register. Bits 7 to 0 are always read
W
as 1.
