SPI/I2C UART with 128-Word FIFOs
The XOFF1 and XOFF2 register contents define the XOFF characters for auto XON/XOFF flow control and/or special
characters used in special character detection. See details in the FlowCtrl register description.
Bits 7–0: Bit[7:0]
These bits define the XOFF2 character if auto software flow control is enabled in FlowCntrl[7:4]. If double-char-
acter flow control is selected in FlowCntrl[7:4], these bits constitute the MSB of the XOFF character. If special
character detection is enabled in MODE2[4] and auto flow control is not enabled, these bits define a special
character. If both special character detection and auto flow control are enabled (MODE2[4] and FlowCntrl[3]),
these bits define a special character.
The four GPIOs can be configured as inputs or outputs and can be operated in push-pull or open-drain mode. The
reference clock has to be active for the GPIOs to work.
Bits 7–4: GP[3:0]OD
Set the GP[3:0]OD bits to 1 to configure open-drain output or input operation. If GP[3:0]OD are 0 (default), the
GPIO_are push-pull outputs, if configured as outputs in GPIOConfg[3:0]. If configured as inputs in GPIOConfg[3:0],
the GPIO_ are high-impedance inputs with weak pulldowns.
Bits 3–0: GP[3:0]Out
The GP[3:0]Out bits configure the GPIO_ to be inputs or outputs. Set the GP[3:0]Out bits high to configure the associ-
ated GPIO_ as outputs. The GP[3:0]Out bits which are set low, are configured to be inputs.
Bits 7–4: GPI[3:0]Dat
The GPI[3:0]Dat bits reflect the logic on GPIO_ when configured as inputs through GPIOConfg[3:0].
Bits 3–0: GPO[3:0]Dat
The GPO[3:0]Dat bits allows programming the logic state of the GPIO_, when these are configured as outputs through
GPIOConfg[3:0]. For open-drain operation, pullup resistors are needed on GPIO_.
