15.4.14 PWM Generator x I/O Control 2 Register
- This bit applies to operation in
complementary mode only. When the outputs are swapped, PGxIOCON1.SWAP =
1, the priority is observed based on Figure 15-5. - The PWM PGx FRZ bits are controlled by MPLAB® IDE. To access the peripheral FRZ bit, open Project Properties and navigate to the options for the debugger being used (such as ICDx). From the option categories drop-down, select Freeze Peripherals, then select the PWM PGx instance. By default, the FRZ bit is set when Debug mode is entered.

Bit 23 – CLMOD Current Limit Mode Select bit(1)
| Value | Description |
|---|---|
1 |
If PCI current limit is active, then the PWMxH and PWMxL output signals are inverted (bit flipping), and the CLDAT[1:0] bits are not used. |
0 |
If PCI current limit is active, then the CLDAT[1:0] bits define the PWM output levels. |
Bit 21 – OVRENH User Override Enable for PWMxH Pin bit
| Value | Description |
|---|---|
| 1 | OVRDAT[1] provides data for output on PWMHx pin. |
| 0 | PWM generator provides data for PWMHx pin. |
Bit 20 – OVRENL User Override Enable for PWMxL Pin bit
| Value | Description |
|---|---|
1 |
OVRDAT[0] provides data for output on the PWMxL pin. |
0 |
PWM Generator provides data for the PWMxL pin. |
Bits 13:12 – OVRDAT[1:0] Data for PWMxH/PWMxL Pins if Override is Enabled bits

Bits 11:10 – OSYNC[1:0] User Output Override Synchronization Control bits
| Value | Description |
|---|---|
11 |
User output
overrides via the SWAP, OVRENL/H and OVRDAT[1:0] bits are synchronized to the data
buffer update of the selected PWM mode. This makes this setting equivalent to
setting 10 when UPDMOD[2:0] = 000 with UPDREQ
properly set manually. |
10 |
User output overrides via the SWAP, OVRENL/H and OVRDAT[1:0] bits occur when specified by the UPMOD[2:0] bits in the PGxCON register. |
01 |
User output overrides via the SWAP, OVRENL/H and OVRDAT[1:0] bits occur immediately (as soon as possible). |
00 |
User output overrides via the SWAP, OVRENL/H and OVRDAT[1:0] bits are synchronized to the local PWM time base (next start of cycle). |
Bits 9:8 – FLT2DAT[1:0] Data for PWMHx/Lx Pins if the FLT Event is Active bits
| Description |
|---|
| If Fault active, then FLT2DAT[1] provides data for PWMHx. |
| If Fault active, then FLT2DAT[0] provides data for PWMLx. |
Bits 7:6 – FLT1DAT[1:0] Data for PWMHx,Lx Pins if FLT Event is Active bits
| Description |
|---|
| If Fault active, then FLT1DAT[1] provides data for PWMHx. |
| If Fault active, then FLT1DAT[0] provides data for PWMLx. |
Bits 5:4 – CLDAT[1:0] Data for PWMxH/PWMxL Pins if CLMT Event is Active bits
| Description |
|---|
| If current limit is active, then CLDAT[1] provides data for PWMxH. |
| If current limit is active, then CLDAT[0] provides data for PWMxL. |
Bits 3:2 – FFDAT[1:0] Data for PWMHx/Lx Pins if the Feed-Forward Event is Active bits
| Description |
|---|
| If feed-forward is active, then FFDAT[1] provides data for PWMxH. |
| If feed-forward is active, then FFDAT[0] provides data for PWMxL. |
Bits 1:0 – DBGDAT[1:0] Data for PWMHx/Lx Pins if Debug Mode is Active bits(2)
| Description |
|---|
|
If Debug mode is active and Freeze peripherals is selected in Project Properties in MPLAB IDE, then DBGDAT[1] provides data for PWMxH. |
|
If Debug mode is active and Freeze peripherals is selected in Project Properties in MPLAB IDE, then DBGDAT[0] provides data for PWMxL. |
