Trace Advance Trigger Select Register - Write Only
D15-D8
Sets the TTLTRIG line or lines, which are configured as outputs, and
will toggle when Trace Advance condition occurs in the module.
D15 corresponds to TTLTRIG7, D14 to TTLTRIG6, … and D8 to
TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a bit
to 0 disables the corresponding line. All bits are set to 0s when either
a soft or a hard reset is received by the module.
D7-D0
Sets the TTLTRIG line or lines, which are configured as inputs, and
will cause a Trace Advance event to occur in the module. D7
corresponds to TTLTRIG7, D6 to TTLTRIG6, … and D0 to
TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a bit
to 0 disables the corresponding line. All enabled TTLTRIG lines are
or'd together to allow more than one TTLTRIG line to cause a Trace
Advance event to occur. All bits are set to 0s when the module
receives either a soft or a hard reset.
Open Trigger Select Register - Write Only
D15-D8
Sets the TTLTRIG line or lines, which are configures as outputs, and
will toggle when Relay Open condition occurs in the module. D15
corresponds to TTLTRIG7, D14 to TTLTRIG6, … and D8 to
TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a bit
to 0 disables the corresponding line. All bits are set to 0s when either
a soft or a hard reset is received by the module.
D7-D0
Sets the TTLTRIG line or lines, which are configured as inputs, and
will cause a Relay Open event to occur in the module. D7
corresponds to TTLTRIG7, D6 to TTLTRIG6, … and D0 to
TTLTRIG0. Setting a bit to a 1 enables the trigger line, setting a bit
to 0 disables the corresponding line. All enabled TTLTRIG lines are
or'd together to allow more than one TTLTRIG line to cause a Relay
Open event to occur. All bits are set to 0s when the module receives
either a soft or a hard reset.
TTL Trigger Polarity Register - Write Only
D15-D14
Unused
Data written to these bits have no effect.
D13-D8
FAIL LED Control
D13 is for module 5, … D8 is for module 0. 0 = off, 1 = on.
D4
Board Busy Trigger Slope
0 acts on the falling edge, 1 acts on the rising edge.
D3
Relay Open Input Slope
0 acts on the falling edge, 1 acts on the rising edge.
D2
Relay Open Output Slope
0 sets the falling edge active, 1 sets the rising edge active.
D1
Trace Advance Input
Slope
0 advances on the falling edge, 1 advances on the rising edge.
D0
Trace Advance Output
Slope
0 sets the falling edge active, 1 sets the rising edge active.
Note
: A hard or a soft reset sets D3-D0 to 0s.
