4.11.17.12.9.6 Show first falling trigger edge
Name:
BusyTriggerFallingCH01 to BusyTriggerFallingCH08
If edges are triggered via the bits in the 4.11.17.12.9.4 "TriggerFallingCH" register, then a set bit in this register
indicates that no falling edges have been detected on the respective channel since the corresponding bit was
set in the "TriggerFallingCH" register. If a falling edge occurs on the respective channel, then the corresponding
BusyTriggerFalling bit is cleared.
Data type Value
USINT See bit structure.
Bit structure:
Bit Description Value Information
0 Falling edge detected on channel 1 0 BusyTriggerFallingCH01
1 Module waiting for a falling edge on channel 1
... ...
0 Falling edge detected on channel 8 7 BusyTriggerFallingCH08
1 Module waiting for a falling edge on channel 8
4.11.17.12.9.7 Show first rising trigger edge
Name:
BusyTriggerRisingCH01 to BusyTriggerRisingCH08
If edges are triggered via the bits in the 4.11.17.12.9.5 "TriggerRisingCH" register, then a set bit in this register
indicates that no rising edges have been detected on the respective channel since the corresponding bit was
set in the "TriggerRisingCH" register. If a rising edge occurs on the respective channel, then the corresponding
BusyTriggerRising bit is cleared.
Data type Value
USINT See bit structure.

0 Rising edge detected on channel 1 0 BusyTriggerRisingCH01
1 Module waiting for a rising edge on channel 1

4.11.17.12.9.8 Count falling trigger edges
Name:
CountFallingCH01 to CountFallingCH08
These registers contain cyclic counters that are incremented with every detected falling edge on the respective
channel.
Data type Value Information
USINT 0 to 255 Counter for falling edges
4.11.17.12.9.9 Count rising trigger edges
Name:
CountRisingCH01 to CountRisingCH08
These registers contain cyclic counters that are incremented with every detected rising edge on the respective
channel.
Data type Value Information
USINT 0 to 255 Counter for rising edges
4.11.17.12.9.10 Time stamp of falling edge
Name:
TimeStampFallingCH01 to TimeStampFallingCH08
When a falling edge occurs on the respective channel, the current counter value of the module timer is copied
to these registers.
Data type Value Information
UINT 0 to 65,535 Time stamp for rising edges
