PDBx_SC field descriptions (continued)
Field Description
7
PDBEN
PDB Enable
0 PDB disabled. Counter is off.
1 PDB enabled.
6
PDBIF
PDB Interrupt Flag
This field is set when the counter value is equal to the IDLY register. Writing zero clears this field.
5
PDBIE
PDB Interrupt Enable
Enables the PDB interrupt. When this field is set and DMAEN is cleared, PDBIF generates a PDB
interrupt.
0 PDB interrupt disabled.
1 PDB interrupt enabled.
4
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
3–2
MULT
Multiplication Factor Select for Prescaler
Selects the multiplication factor of the prescaler divider for the counter clock.
00 Multiplication factor is 1.
01 Multiplication factor is 10.
10 Multiplication factor is 20.
11 Multiplication factor is 40.
1
CONT
Continuous Mode Enable
Enables the PDB operation in Continuous mode.
0 PDB operation in One-Shot mode
1 PDB operation in Continuous mode
0
LDOK
Load OK
Writing 1 to LDOK bit updates the MOD, IDLY, CHnDLYm, DACINTx, and POyDLY registers with the
values previously written to their internal buffers (and stored there). The new values of MOD, IDLY,
CHnDLYm, DACINTx, and POyDLY registers will take effect according to the setting of the LDMOD field
(Load Mode Select). Before 1 is written to the LDOK field, the values in the internal buffers of these
registers are not effective, and new values cannot be written to the internal buffers until the existing values
in the internal buffers are loaded into their corresponding registers.
• LDOK can be written only when PDBEN is set, or LDOK can be written at the same time when
PDBEN is written to 1.
• LDOK is automatically cleared when the values in the internal buffers are loaded into the registers or
when PDBEN bit (PDB Enable) is cleared.
• Writing 0 to LDOK has no effect.
