RFALL

The Master Interface Configuration Register is provided at D3MX read/write

address 05H.

RFALL:

The receive falling edge select (RFALL) bit configures the sampling edge

used on the DS3 receive interface. When RFALL is a logic 1, the DS3 receive

interface is sampled on the falling edge of RCLK. When RFALL is a logic 0,

the DS3 receive interface is sampled on the rising edge of RCLK.

RINV:

The receive invert (RINV) bit enables data inversion of the DS3 receive

interface. When RINV is a logic 1, the RPOS and RNEG signals are active

low. When RINV is a logic 0, the RPOS and RNEG signals are active high.

Inversion only takes place when the DS3 receive interface is configured for

dual rail operation.

TUNI:

The transmit unipolar (TUNI) bit configures the DS3 transmit interface for

unipolar or dual rail operation. When TUNI is a logic 1, the DS3 transmit

interface is configured as TDAT and TMFP. When TUNI is a logic 0, the DS3

transmit interface is configured as TPOS and TNEG.

TRISE:

The transmit falling edge select (TRISE) bit configures the updating edge

used on the DS3 transmit interface. When TRISE is a logic 1, the DS3
