Interpreting the Digital Monitor Output

This section describes which bits of the DMONITOROUT bus are relevant for the appropriate

selection of DMON_CFG and the manner of interpreting the output.

• RXLPMOS[6:0] = DMONITOROUT[6:0]

7'd0 = –Full scale

7'd63, 7'd64 = 0

7'd127 = +Full scale

• RXLPMHF [3:0] = RXLPMLF [3:0] = DMONITOROUT[6:3]

4'd0 = 0

4'd15 = Full scale
