X = Don’t care
XON1 Register
The XON1 and XON2 register contents define the XON characters used for auto XON/XOFF flow control and/or the
special characters used for special character detection. See details in the FlowCtrl register description.
Bits 7–0: Bit[7:0]
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 con-
trol character.
