XON2 Register
The XON1 and XON2 register contents define the XON characters for auto 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[7:0]
These bits define the XON2 character if single-character auto software flow control is enabled in FlowCntrl[7:4]. If dou-
ble-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 software flow control are enabled (MODE2[4] and FlowCntrl[3]),
these bits define a special character.
XOFF1 Register
The XOFF1 and XOFF2 register contents define the XOFF characters for auto 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[7:0]
These bits define the XOFF1 character if single-character XOFF 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 XOFF 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 special character detection and software flow control are both enabled, XOFF1 defines the XOFF
flow control character.
