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 2
(GPIO_DIR_2), 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 2 (GPIO_2)
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 2 (GPIO_2) 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
