Table 7.4.7.1
GpioDir -
this parameter is a bitmask that sets whether each GPIO is an input (0) or outputs (1). The default is all inputs.
GpioInit
- this parameter is a bitmask that sets the initial value for any GPIOs which are enabled as outputs. For GPIOs
enabled as inputs, this sets the initial pull-up setting.
GpioAlt
- Specifies which GPIO pins will have their alternate functions enabled: Bit 2 - diversity toggle enable, Bit 3 -
RS485 enable, Bit 4 - /HOST_CTS enable, Bit5 - /HOST_RTS enable.
