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).
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 6
(GPIO_DIR_6), 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 6 (GPIO_6)
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 6 (GPIO_6) within the “Operation General Purpose
Input/Output Register – Byte 0” (Address Location = 0x0147).
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).
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 7 (GPIO_7) within the “Operation General Purpose
Input/Output Register – Byte 0” (Address Location = 0x0147).
