Output
U22 The Receive Cell Data (RDAT[15:0]) signals carry
T22 the ATM cell words that have been read from the
U19 S/UNI-IMA-8 internal cell buffers. When this
R20 interface is operating in 8-bit mode, the data is
R22 carried on RDAT[7:0].
T19
The RDAT[15:0] output bus is updated on the rising
R19
edge of RCLK.

RPRTY
Output
M22 The Receive Parity (RPRTY) signal provides the
parity (programmable for odd or even parity) of the
RDAT[15:0] bus. When the interface is operating in
8-bit mode, the parity is calculated over RDAT[7:0]
The RPRTY output is updated on the rising edge of
RCLK.
