SR/DR
Single-rail/Dual-rail Select:
Writing a “1” to this bit configures
all 8 channels in the XRT83SH38 to operate in the Single-rail
mode.
Writing a “0” configures the XRT83SH38 to operate in Dual-rail
mode.
R/W
0
D6
ATAOS
Automatic Transmit All Ones Upon RLOS:
Writing a “1” to
this bit enables the automatic transmission of All "Ones" data
to the line for the channel that detects an RLOS condition.
Writing a “0” disables this feature.
R/W
0
D5
RCLKE
Receive Clock Edge:
Writing a “1” to this bit selects receive
output data of all channels to be updated on the negative edge
of RCLK.
Wring a “0” selects data to be updated on the positive edge of
RCLK.
R/W
0
D4
TCLKE
Transmit Clock Edge:
Writing a “0” to this bit selects transmit
data at TPOS_n/TDATA_n and TNEG_n/CODES_n of all
channels to be sampled on the falling edge of TCLK_n.
Writing a “1” selects the rising edge of the TCLK_n for sam-
pling.
R/W
0
D3
DATAP
DATA Polarity:
Writing a “0” to this bit selects transmit input
and receive output data of all channels to be active “High”.
Writing a “1” selects an active “Low” state.

GIE
Global Interrupt Enable:
Writing a “1” to this bit globally
enables interrupt generation for all channels.
Writing a “0” disables interrupt generation.

SRESET
Software Reset
μ
P Registers:
Writing a “1” to this bit longer
than 10μs initiates a device reset through the microprocessor
interface. All internal circuits are placed in the reset state with
this bit set to a “1” except the microprocessor register bits.
