4-CH FULL-SPEED USB UART
GPIO_INT_MASK[5:0]: GPIOx Interrupt Mask
Logic 0 = A change on this input causes the device to generate an interrupt packet.
Logic 1 = A change on this input does not cause the device to generate an interrupt packet.
GPIO_INT_MASK[7:6]: Reserved
These register bits are reserved and should be ’0’.
3.3.15
GPIO_SET Register Description (Read/Write)
Writing a ’1’ in this register drives the GPIO output high. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
3.3.16
GPIO_CLEAR Register Description (Read/Write)
Writing a ’1’ in this register drives the GPIO output low. Writing a ’0’ to a bit has no effect. Bits 7-6 are unused
and should be ’0’.
3.3.17
GPIO_STATUS Register Description (Read-Only)
This register reports the current state of the GPIO pin.
