40.3.16 Pulse-Out n Delay register (PDBx_POnDLY)
Note: This register is internally buffered, and any values written to the register are
written to its internal buffer instead; in other words, the internal device bus does not write
directly to this register. The value in this register's internal buffer is loaded into this
register only after "1" is written to the SC[LDOK] bit.
Address: Base a 194h (4d × i), where i=0d to 0d

DLY1
PDB Pulse-Out Delay 1
These bits specify the delay 1 value for the PDB Pulse-Out. Pulse-Out goes high when the PDB counter is
equal to the DLY1. Reading these bits returns the value of internal register that is effective for the current
PDB cycle.
DLY2 PDB Pulse-Out Delay 2
These bits specify the delay 2 value for the PDB Pulse-Out. Pulse-Out goes low when the PDB counter is
equal to the DLY2. Reading these bits returns the value of internal register that is effective for the current
PDB cycle.
40.4 Functional description
40.4.1 PDB pre-trigger and trigger outputs
The PDB contains a counter whose output is compared to several different digital values.
If the PDB is enabled, then a trigger input event will reset the counter and make it start to
count. A trigger input event is defined as a rising edge being detected on a selected
trigger input source, or if a software trigger is selected and the Software Trigger bit
(SC[SWTRIG]) is written with 1. For each channel, a delay m determines the time
between assertion of the trigger input event to the time at which changes in the pre-
trigger m output signal are started. The time is defined as:
