Bits 7 and 6: No Function
Bit 5: 4xMode
When the 4xMode bit is set high, the MAX3107 baud rate is quadruple the regular (16x sampling) baud rate. The
2xMode bit should be set low if 4xMode is enabled. See the 2x and 4x Rate Modes section for more information.
Bit 4: 2xMode
When the 2xMode bit is set high, the MAX3107 baud rate is double the regular (16x sampling) baud rate. See the 2x
and 4x Rate Modes section for a detailed description.
Bits 3–0: FRACT[3:0]
This is the fractional portion of the baud-rate generator divisor. Set FRACT[3:0] to zero if not used. See the Fractional
Baud-Rate Generator section for calculations.
DIVLSB and DIVMSB define the baud-rate generator integer divisors. The minimum value is 1. See the Fractional Baud
Rate Generator section for more information.
Bits 7–0: Div[7:0]
Div[7:0] are the 8 LSBs of the integer divisor portion (DIV) of the baud-rate generator.
Bits 7–0: Div[15:8]
Div[15:8] is the MSB portion of the integer divisor (DIV).
