General Purpose Output 6~4 (in 8-bit mode)
These bits are reflect to pin GP6~4 respectively.
General Purpose (in 8-bit mode)
When the correspondent bit of General Purpose Control Register is 1, the value of
the bit is reflected to pin GP3~1 respectively.
When the correspondent bit of General Purpose Control Register is 0, the value of
the bit to be read is reflected from correspondent pins of GP3~1 respectively.
