P17–P10, GPIO Port 1 data:
When programmed as an output, the GPIO port 1 bit follows the value written into this register and
reads reflect the value written.
When programmed as inputs, writes are ignored and a read follows the state of the GPIO port 1
signal. Direction control is via the GPIO port 2 and control register.

P21 – P20, GPIO Port 2 data:
When programmed as an output, the GPIO port 2 bit follows the value written into this register and
reads reflect the value written. When programmed as inputs, writes are ignored and a read follows
the state of the GPIO port 2 signal. Direction control is via the D201 control.
P22, GPIO Port 2 data:
This bit is output only. GPIO port 2 bit 2 follows the value written into this register and reads reflect
the value written.
