4.11.14.12.9.5 Trigger rising edge detection
Name:
TriggerRisingCH01 to TriggerRisingCH04
If bit 7 "Trigger" is cleared in the 4.11.14.12.9.3 "CfO_EdgeTimeRisingMode" register, then detection of a rising
edge on the respective input can be triggered using the respective bit in this register. After a bit has been set, the
next rising edge on the corresponding channel is detected.

4.11.14.12.9.6 Show first falling trigger edge
Name:
BusyTriggerFallingCH01 to BusyTriggerFallingCH04
If edges are triggered via the bits in the 4.11.14.12.9.4 "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.

4.11.14.12.9.7 Show first rising trigger edge
Name:
BusyTriggerRisingCH01 to BusyTriggerRisingCH04
If edges are triggered via the bits in the 4.11.14.12.9.5 "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.
