The bottom data input bus (DINB[8:0]) carries
SONET/SDH frame data in byte serial format. The
DINT[8] bit is a parity bit which is not passed through
the TUDX. The TUDX may be configured to check for
even or odd input bus parity and generate interrupts
when parity errors occur. The DINB[8:0] bus is
sampled on the rising edge of SCLK.

SONET/SDH frame data in byte serial format. The
DOUTL[8] bit is a parity bit which is generated by the
TUDX. The TUDX may be configured to generate
even or odd parity. The DOUTL[8:0] bus is updated on
the rising edge of SCLK. DOUTL may be configured
as a normal output or as an open drain output, the
latter mode being useful for constructing larger
switching arrays.

The right data output bus (DOUTR[8:0]) carries
SONET/SDH frame data in byte serial format. The
DOUTR[8] bit is a parity bit which is generated by the
TUDX. The TUDX may be configured to generate
even or odd parity. The DOUTR[8:0] bus is updated
on the rising edge of SCLK. DOUTR may be
configured as a normal output or as an open drain
output, the latter mode being useful for constructing
larger switching arrays.
