11.7 GPIO_3_Config Register (Address = Fh) [reset = 0h]

GPIO_3_Config is described in Table 11-6.

Table 11-6 GPIO_1_and_GPIO_2_Config Register Field Descriptions
BitFieldTypeResetDescription
7-4RESERVEDR/W0hGPIO3 and D_GPIO3 Configuration.
If PORT1_SEL is set ,this register controls the D_GPIO3.
Local GPIO Output Value.
This value is output on the GPIO pin when the GPIO function is enabled, the local GPIO direction is Output, and remote GPIO control is disabled. This value is also output to the GPIO pin in Remote_Default mode if the link is lost.
3GPIO3_OUTPUT_VALUE_D_GPIO3_OUTPUT_VALUER/W0hLocal GPIO Output Value.
This value is output on the GPIO pin when the GPIO function is enabled, the local GPIO direction is Output, and remote GPIO control is disabled. This value is also output to the GPIO pin in Remote-Default mode if the link is lost.
2-0GPIO1_MODE_D_GPIO3_MODER/W0hGPIO 3 Mode.
Determines operating mode for the GPIO pin:
x00: Functional input mode, I2S_DC input
x10: Tri-State
001: GPIO mode, output
011: GPIO mode, input
101: Remote-Hold - output remote data, maintain data on link-loss
111: Remote-Default - output remote data Drive default data (OUTPUT VALUE) on link-loss
