GPIOData—GPIO Data Register
Bits 7–4: GPI[n]Dat
Each UART has four individually assigned GPIO outputs as follows: UART0: GPIO0–GPIO3, UART1: GPIO4–GPIO7,
UART2: GPIO8–GPIO11, UART3: GPIO12–GPIO15. For example, for UART0: Bit 4 is GPI0Dat, Bit 5 is GPI1Dat, Bit 6 is
GPI2Dat, and Bit 7 is GPI3Dat (see Table 6).
The GPI[n]Dat bits reflect the logic on the GPIO_s.
Bits 3–0: GPO[n]Dat
Each UART has four individually assigned GPIO outputs as follows: UART0: GPIO0–GPIO3, UART1: GPIO4–GPIO7,
UART2: GPIO8–GPIO11, UART3: GPIO12–GPIO15. For example, for UART0: Bit 0 is GPO0Dat, Bit 1 is GPO1Dat, Bit
2 is GPO2Dat, and Bit 3 is GPO3Dat (see Table 6).
The GPO[n]Dat bits allow programming the logic state of the GPIO_, when configured as outputs in GPIOConfg[3:0].
For open-drain operation, pullup resistors are needed on GPIO_.
