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 SWTRIG
resets and restarts the counter. Writing 0 to SWTRIG has no effect. Reading SWTRIG yields 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
Counting uses the peripheral clock divided by the product of a factor (selected by MULT field) and an
integer factor (set by PRESCALAR field), or in other words, (peripheral clock)/(MULT x PRESCALAR).
000 Counting uses the peripheral clock divided by MULT (the multiplication factor).
001 Counting uses the peripheral clock divided by 2 x MULT (the multiplication factor).
010 Counting uses the peripheral clock divided by 4 x MULT (the multiplication factor).
011 Counting uses the peripheral clock divided by 8 x MULT (the multiplication factor).
100 Counting uses the peripheral clock divided by 16 x MULT (the multiplication factor).
101 Counting uses the peripheral clock divided by 32 x MULT (the multiplication factor).
110 Counting uses the peripheral clock divided by 64 x MULT (the multiplication factor).
111 Counting uses the peripheral clock divided by 128 x MULT (the multiplication factor).
11–8
TRGSEL
Trigger Input Source Select
Selects the trigger input source for the PDB. The trigger input source can be internal or external (EXTRG
pin), or the software trigger. Refer to chip configuration details for the actual PDB input trigger
connections.
0000 Trigger-In 0 is selected.
0001 Trigger-In 1 is selected.
0010 Trigger-In 2 is selected.
0011 Trigger-In 3 is selected.
0100 Trigger-In 4 is selected.
0101 Trigger-In 5 is selected.
0110 Trigger-In 6 is selected.
0111 Trigger-In 7 is selected.
1000 Trigger-In 8 is selected.
1001 Trigger-In 9 is selected.
1010 Trigger-In 10 is selected.
1011 Trigger-In 11 is selected.
1100 Trigger-In 12 is selected.
1101 Trigger-In 13 is selected.
1110 Trigger-In 14 is selected.
1111 Software trigger is selected.
