Programming Information
Bit Name
Default
Bit No.
When the GPIO[1] pin is defined as an output port, this bit can be read and written:
= 0: The GPIO[1] pin outputs low level.
= 1: The GPIO[1] pin outputs high level.
When the GPIO[1] pin is defined as an input port, this bit can only be read:
= 0: Low level is input on the GPIO[1] pin.
= 1: High level is input on the GPIO[1] pin.
When the GPIO[0] pin is defined as an output port, this bit can be read and written:
= 0: The GPIO[0] pin outputs low level.
= 1: The GPIO[0] pin outputs high level.
When the GPIO[0] pin is defined as an input port, this bit can only be read:
= 0: Low level is input on the GPIO[0] pin.
= 1: High level is input on the GPIO[0] pin.
= 0: The GPIO[1] pin is used as an output port.
= 1: The GPIO[1] pin is used as an input port.
= 0: The GPIO[0] pin is used as an output port.
= 1: The GPIO[0] pin is used as an input port.
