GPIO_MODE Register Description (Read/Write)
GPIO_MODE[2:0]: GPIO Mode Select
There are 4 modes of operation for the GPIOs. The descriptions can be found in “Section 1.5, UART” on
page 7.
GPIO_MODE[3]: RS485 Polarity
Logic 0 = GPIO5/RTS#/RS485 Low for TX
Logic 1 = GPIO5/RTS#/RS485 High for TX
GPIO_MODE[7:4]: Reserved
These register bits are reserved. When writing to these bits, the value should be ’0’. When reading from these
bits, they are undefined and should be ignored.
3.3.13
GPIO_DIRECTION Register Description (Read/Write)
This register controls the direction of pins configured as GPIO. (Pins configured for UART functions via the
GPIO_MODE register, e.g. RTS# are not controlled or reported in the GPIO_DIRECTION register.)
GPIO_DIRECTION[5:0]: GPIOx Direction
Logic 0 = GPIOx is an input.
Logic 1 = GPIOx is an output.
GPIO_DIRECTION[7:6]: Reserved
These register bits are reserved and should be ’0’.
3.3.14
GPIO_INT_MASK Register Description (Read/Write)
Enables / disables generation of a USB interrupt packet at the change of state of GPIO pins when they are
configured as inputs.
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’.
