GPIO1 Part
This part contains:
General Purpose I/O Function
Default is General Purpose I/O. Change the value of GPIO1 and GPIOD1 register to determine 8
input/output.
Keyboard Matrix Column Output
Use Chipctrl2 register bit 3 to enable {GP0, GP1, GP20~23} keyboard scan and GP3 key wakeup
interrupt function.
Internal Flash Access Interface
When TEST# and RESET# are both low, Internal Flash Access Interface is enabled and other
functions are disabled.
