RNEGINV

RNEGINV:

The RNEGINV bit provides polarity control for input RNEG/RLCV/ROHM.

When a logic 0 is written to RNEGINV, the input RNEG/RLCV/ROHM is not

inverted. When a logic 1 is written to RNEGINV, the input

RNEG/RLCV/ROHM is inverted. The RNEGINV bit setting does not affect the

loopback data in diagnostic loopback.

RPOSINV:

The RPOSINV bit provides polarity control for input RPOS/RDATI. When a

logic 0 is written to RPOSINV , the input RPOS/RDATI is not inverted. When

a logic 1 is written to RPOSINV , the input RPOS/RDATI is inverted. The

RPOSINV bit setting does not affect the loopback data in diagnostic

loopback.

RCLKINV:

The RCLKINV bit provides polarity control for input RCLK. When a logic 0 is

written to RCLKINV, RCLK is not inverted and inputs RPOS/RDATI and

RNEG/RLCV/ROHM are sampled on the rising edge of RCLK. When a logic

1 is written to RCLKINV, RCLK is inverted and inputs RPOS/RDATI and

RNEG/RLCV/ROHM are sampled on the falling edge of RCLK.

RSCLKR:

The RSCLKR bit has effect only when the FRMRONLY bit in the S/UNI-QJET

Configuration 1 register is set to logic 1. When RSCLKR is a logic 1, the

RDATO, RFPO/RMFPO, and ROVRHD outputs are updated on the rising
