6.6.1 GPIO Data Register Description
6.6.1.1 GPIO 0 Input/Output Register (GPIO0) (Default Value: 0000_0000)
Write:
Output data register
Read:
GPIO pin status whether GPIO function is active or not.
Note: bit command and byte command have same result.
For example “CPL Bit” Instruction
Read Pin Status into temp Register.
Invert temp register.
Write Result to Output Data Register according for bit address, and not influence the value of other
bit.
6.6.1.2 GPIO 1 Input/Output Register (GPIO1) (Default Value: 0000_0000)
Write:
Output data register
Read:
GPIO pin status whether GPIO function is active or not.
Note: bit command and byte command have same result
