AC26
GPIO_5
I/O
TTL/CMOS
General Purpose Input/Output pin
This input pin can be configured to function as either an input
or output pin by writing the appropriate value into Bit
35(GPIO_DIR_5), within the “Operation General Purpose
Input/Output Direction Register – 0” (Address Location
=
0x014B).
If this pin is configured to be an input pin, then the state of this
pin can be monitored by reading the state of Bit 5 (GPIO_5)
within the “Operation General Purpose Input/Output Register –
Byte 0” (Address Location = 0x0147).
If this pin is configured to be an output pin, then the state of
this pin can be controlled by writing the appropriate value into
Bit 5 (GPIO_5) within the “Operation General Purpose
Input/Output Register – Byte 0” (Address Location = 0x0147).

If this pin is configured to be an input pin, then the state of this
pin can be monitored by reading the state of Bit 6 (GPIO_6)
within the “Operation General Purpose Input/Output Register –

General Purpose Input/Output pin
This input pin can be configured to function as either an input
or output pin by writing the appropriate value into Bit 7
(GPIO_DIR_7),
within
the
“Operation
General
Purpose
Input/Output Direction Register – 0” (Address Location
=
0x014B).
If this pin is configured to be an input pin, then the state of this
pin can be monitored by reading the state of Bit 7 (GPIO_7)
within the “Operation General Purpose Input/Output Register –
Byte 0” (Address Location = 0x0147).
