SPI/I2C UART with 128-Word FIFOs
Bits 7–4: SwFlow[3:0]
The SwFlow[3:0] bits configure auto software flow control and/or special character detection in combination with the
characters defined in the XON1, XON2, XOFF1 and/or XOFF2 registers. See Table 3.
FlowCtrl[5:4] select which of the XON1, XON2, XOFF1 or/and XOFF2 characters are used for special character detec-
tion and/or auto flow control. If auto receiver flow control is enabled through SwFlowEn and FlowCtrl[7:6], the XON and
XOFF characters that the MAX3107 receives are filtered out and are not put into the RxFIFO. Set the SwFlowEn bit to
0 and set MODE2[4] to 1 to only enable special character detection. Under these conditions, auto flow transmit flow
control is not active.
If both special character detection (MODE2[4]) and auto software flow control (FlowCtrl[3]) are to be enabled, XON1
and XOFF1 define the auto flow control characters, while XON2 and XOFF2 define the special character detection
characters.
Bit 3: SwFlowEn
The SwFlowEn bit enables auto software flow control. The characters used for auto software flow control are selected in
SwFlow[7:4]. If special character detection (MODE2[4] set to 1) is used in addition to auto software flow control, XON1
and XOFF1 are used for flow control, while XON2 and XOFF2 define the special characters.
Bit 2: GPIAddr
The GPIAddr bit, when set, enables that the four GPIO_ inputs are used in conjunction with XOFF2 for the definition of a
special character. This can be used, for example, for defining the address of a RS-485 slave device through hardware.
The GPIO_ inputs logic levels, which define the 4 LSBs of the special character, while the 4 MSBs are defined by the
XOFF2[7:4] bits. If GPIAddr is set, the contents of the XOFF2[3:0] bits are neglected. In this case, the XOFF2[3:0] bits,
when read, also do not reflect the logic on GPIO_.
Bit 1: AutoCTS
The AutoCTS bit enables auto CTS flow control by which the transmitter stops and starts sending data depending on
the logic state at the CTS input. See the Auto Hardware Flow Control section for a description of AutoCTS flow con-
trol. Logic changes at the CTS input result in an ISR[7]: CTSInt interrupt. The transmitter must be turned off by setting
MODE1[1] to 1 before AutoCTS is enabled.
Bit 0: AutoRTS
The AutoRTS bit enables auto RTS flow control by which the MAX3107 sets its RTS/CLKOUT output dependent on
the receive FIFO fill level. The FIFO thresholds at which RTS/CLKOUT changes state are set in FlowLvl. See the Auto
Hardware Flow Control section for more information.
