PDBx_SC field descriptions (continued)
Field
Description
10
The internal registers are loaded with the values from their buffers when a trigger input event is
detected, after 1 is written to LDOK.
11
The internal registers are loaded with the values from their buffers when either the PDB counter
(CNT) = MOD + 1 CNT delay elapsed, or a trigger input event is detected, after 1 is written to LDOK.
17
PDBEIE
PDB Sequence Error Interrupt Enable
Enables the PDB sequence error interrupt. When PDBEIE is set, any of the PDB channel sequence error
flags generates a PDB sequence error interrupt.
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.
