These bits define the XON1 character if single character XON auto software flow control is enabled in FlowCntrl[7:4]. If
double character flow control is selected in FlowCntrl[7:4], these bits constitute the LSB of the XON character. If special
character detection is enabled in MODE2[4] and auto flow control is not enabled, these bits define a special character.
If special character detection and auto software flow control are enabled, XON1 defines the XON flow control character.
The XON1 and XON2 register contents define the XON characters for automatic XON/XOFF flow control and/or the
special characters used in special character detection. See details in the FlowCtrl register description.

Bits 7–0: Bit[n]
These bits define the XON2 character if single character auto software flow control is enabled in FlowCntrl[7:4]. If double
character flow control is selected in FlowCntrl[7:4], these bits constitute the MSB of the XON character. If special character
detection is enabled in MODE2[4] and auto software 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 XOFF1 and XOFF2 register contents define the XOFF characters for automatic XON/XOFF flow control and/or the
special characters used in special character detection. See details in the FlowCtrl register description.
