The receive cell data (RDAT[15:0]) bus carries the

ATM cell octets that are read from the receive

FIFO. When the 16-bit SCI-PHY interface is

selected, (BUS8 is tied low), RDAT[15:0] contains

the 16 bit wide word bus. When the 8-bit SCI-

PHY interface is selected (BUS8 is tied high),

RDAT[7:0] contains the 8-bit wide word bus

(RDAT[15:8] is not used). RDAT[15:0] is updated

on the rising edge of RFCLK.

When the S/UNI-PLUS is configured for tristate

operation using the TSEN input, tristating of

output bus RDAT[15:0] is controlled by input

RRDENB.

The receive parity (RXPRTY[1:0]) signals indicate

the parity of the RDAT[15:0] bus. RXPRTY[1] is

the parity calculation over the RDAT[15:8] bus.

RXPRTY[0] is the parity calculation over the

RDAT[7:0] bus. Alternately, the device can be

configured so that RXPRTY[1] is the parity

calculation over the entire RDAT[15:0] bus.

RXPRTY[0] is not used in this case. Odd or even

parity selection can be made using the RACP

Control register. RXPRTY[1:0] is updated on the

rising edge of RFCLK.

When the S/UNI-PLUS is configured for tristate

operation using the TSEN input, tristating of

output bus RXPRTY[1:0] is control by input

RRDENB.
