Information

PDBx_SC field descriptions (continued)
Field Description
0 PDB sequence error interrupt disabled.
1 PDB sequence error interrupt enabled.
16
SWTRIG
Software Trigger
When PDB is enabled and the software trigger is selected as the trigger input source, writing 1 to this bit
reset and restarts the counter. Writing 0 to this bit has no effect. Reading this bit results 0.
15
DMAEN
DMA Enable
When DMA is enabled, the PDBIF flag generates a DMA request instead of an interrupt.
0 DMA disabled
1 DMA enabled
14–12
PRESCALER
Prescaler Divider Select
000 Counting uses the peripheral clock divided by multiplication factor selected by MULT.
001 Counting uses the peripheral clock divided by twice of the multiplication factor selected by MULT.
010 Counting uses the peripheral clock divided by four times of the multiplication factor selected by
MULT.
011 Counting uses the peripheral clock divided by eight times of the multiplication factor selected by
MULT.
100 Counting uses the peripheral clock divided by 16 times of the multiplication factor selected by
MULT.
101 Counting uses the peripheral clock divided by 32 times of the multiplication factor selected by
MULT.
110 Counting uses the peripheral clock divided by 64 times of the multiplication factor selected by
MULT.
111 Counting uses the peripheral clock divided by 128 times of the multiplication factor selected by
MULT.
11–8
