The transmit cell data bus (TDAT[15:0]) carries the
ATM cell octets that are transferred to the internal cell
buffer.
The TDAT[15:0] bus is sampled on the rising edge of
TCLK and is considered valid only when the TENB
signal is asserted low or the TSX signal is asserted
high.
TPRTY
Input
T22
The transmit parity (TPRTY) signal completes the
parity (programmable for odd or even parity) of the
TDAT[15:0] bus.
A parity error is indicated by a status bit and a
maskable interrupt.
The TPRTY signal is sampled on the rising edge of
TCLK and is considered valid only when the TENB
signal is asserted or the TSX signal is asserted high.
Microprocessor Bus
CSB
Input
AA17 The active-low chip select (CSB) signal is low during
S/UNI-VORTEX register accesses.
If CSB is not required (i.e., registers accesses are
controlled using the RDB and WRB signals only), CSB
must be connected to an inverted version of the RSTB
input.
RDB
Input
Y16
The active-low read enable (RDB) signal is low during
S/UNI-VORTEX register read accesses. The S/UNI-
VORTEX drives the D[7:0] bus with the contents of
the addressed register while RDB and CSB are low.
