Bit No.
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[0] pin is used as an output port.
= 1: The GPIO[0] pin is used as an input port.
= 0: Disable the interrupt on the INT pin when the TMOVI bit (b0, T1/J1-00BH) is ‘1’.
= 1: Enable the interrupt on the INT pin when the TMOVI bit (b0, T1/J1-00BH) is ‘1’.
The device times every one second.
= 0: One second timer is not over.
= 1: One second timer is over.
This bit will be cleared if a ’1’ is written to it.
