Output A20 The receive cell data bus (RDAT[15:0]) carries the
C19 ATM cell words that have been read from the S/UNI-
D19 VORTEX internal cell buffers.
D21
The RDAT[15:0] bus is updated on the rising edge of
C23
RCLK and considered valid only when the S/UNI-
D22
VORTEX device was selected after the polling
E21
process and the RENB signal is sampled low. If
D23
RANYPHY is logic low RDAT[15:0] is driven
E22
immediately upon sampling RENB low, but it has an
F21
additional cycle latency when RANYPHY is logic high.
G20
RDAT[15:0] becomes high impedance upon sampling
E23
RENB high or if the S/UNI-VORTEX device is not
F22
selected for transfer.
G21
When RANYPHY is high, autonomous deselection
occurs after the last word of a cell resulting in setting
RDAT[15:0] high-impedance until reselection.
H20
G23
RPRTY
Output B19 The Receive Parity (RPRTY) signal completes the
parity (programmable for odd or even parity) of the
RDAT[15:0] bus.
The RPRTY signal is updated on the rising edge of
RCLK and is considered valid only when the S/UNI-
VORTEX device was selected after the polling
process and the RENB signal is sampled low. If
RANYPHY is logic low RPRTY is driven immediately
upon sampling RENB low, but it has an additional
cycle latency when RANYPHY is logic high. RPRTY
becomes high impedance upon sampling RENB high
or if the S/UNI-VORTEX device is not selected for
transfer.
When RANYPHY is high, autonomous deselection
occurs after the last word of a cell resulting in setting
RPRTY high-impedance until reselection.
