Control and Status Registers 85
5.17.11 GPIO (15-8) Interrupt Non-Maskable Register (Offset
0x686)
For each GPIO:
1 = GPIO interrupt is non-maskable
0 = GPIO interrupt is maskable (default)
Once a GPIO interrupt has been set as non-maskable in this register, it cannot be set
to maskable again until after the next reset has occurred.
5.17.12 GPIO (15-8) Test Mode Register (Offset 0x687)
For each GPIO:
1 = GPIO in test mode (input circuits receive the value in GPIO15-8 Out)
0 = GPIO not in test mode (input circuits receive the pin value) (default).
5.18
GPIO (23-16) Registers
The PPC11A supports up to 19 GPIO lines, so in the following descriptions, bits 2 to
0 of each register map to GPIO pins 18 to 16 respectively. Bits 7 to 3 of each register
are unused/reserved.

5.18.1 GPIO (23-16) Out Register (Offset 0x688)
The value of the bit in this register is driven onto the appropriate GPIO pin when the
corresponding direction is set to output. The default is 0x00.
5.18.2 GPIO (23-16) In Register (Offset 0x689)
The value of the bit in this register returns the status of the appropriate GPIO pin,
regardless of the corresponding direction. The default is 0x07.
5.18.3 GPIO (23-16) Direction Register (Offset 0x68A)
For each GPIO:
1 = Output
0 = Input (default)
