GPIO Input/Output Select Register 2 (Offset G0x34)
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
GPIO7 GPIO6 GPIO5 GPIO4
Bit X = 0 means Output Pin
Bit X = 1 means Input Pin
4.16.2.3 GPIO Level for Input or Output Register 1
(Offset G0x0C)
If Pin X is configured as output, the output value (0 or 1) could be selected by
user.
If it is programmed as an input, this register reflects the state of the input
signal.
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
GPIO3 GPIO2 GPIO1 GPIO0
GPIO Level for Input or Output Register 1
(Offset G0x38)
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
GPIO7 GPIO6 GPIO5 GPIO4
4.16.2.4 GPIO Signal Invert Register (Offset 0x2C)
It will invert the polarity of the Input Port register data.
Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
GPIO3 GPIO2 GPIO1 GPIO0
Bit X = 0 means Polarity is retained
Bit X = 1 means Polarity is inverted
[Note] The GPIO4~GPIO7 can
’t be set to inverted.
