Function
Transmit Data (TDATO[4:1]). TDATO[4:1]
contains the transmit data stream when
the single-rail (unipolar) output format is
enabled
The TDATO[4:1] pin function selection is
controlled by the TFRM[1:0] and the TUNI
bits in the S/UNI-CDB Transmit
Configuration Registers. TDATO[4:1] is
updated on the falling edge of TCLK[4:1]
by default, and may be configured to be
updated on the rising edge of TCLK[4:1]
through the TCLKINV bit in the S/UNI-CDB
Transmit Configuration Registers. Finally,
TDATO[4:1] can be updated on the rising
edge of TICLK[4:1], enabled by the TICLK
bit in the S/UNI-CDB Transmit
Configuration Registers.
