MAX3107

SPI/I

C UART with 128-Word FIFOs

and Internal Oscillator

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[7:0]

These bits define the XON2 character if single-character automatic 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 spe-

cial character detection is enabled in MODE2[4], and automatic software flow control is not enabled, these bits define

a special character. If both special character detection and automatic software 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.

Bits 7–0: Bit[7:0]

These bits define the XOFF1 character if single-character XOFF automatic 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 automatic 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.
