Bit 15 – SEVT PCI Sync Event
| Value | Description |
|---|---|
1 | A PCI Sync event has occurred (rising edge on PCI Sync output or PCI Sync output is high when module is enabled) |
0 | No PCI Sync event has occurred |
Bit 14 – FLTEVT PCI Fault Active Status
| Value | Description |
|---|---|
1 | A Fault event has occurred (rising edge on PCI Fault output or PCI Fault output is high when module is enabled) |
0 | No Fault event has occurred |
Bit 13 – CLEVT PCI Current Limit Status
| Value | Description |
|---|---|
1 | A PCI current limit event has occurred (rising edge on PCI current limit output or PCI current limit output is high when module is enabled) |
0 | No PCI current limit event has occurred |
Bit 12 – FFEVT PCI Feed-Forward Active Status
| Value | Description |
|---|---|
1 | A PCI feed-forward event has occurred (the rising edge on the PCI feed-forward output or PCI feed-forward output is high when module is enabled) |
0 | No PCI feed-forward event has occurred |
Bit 11 – SACT PCI Sync Status
| Value | Description |
|---|---|
1 | PCI Sync output is active |
0 | PCI Sync output is inactive |
Bit 10 – FLTACT PCI Fault Active Status
| Value | Description |
|---|---|
1 | PCI Fault output is active |
0 | PCI Fault output is inactive |
Bit 9 – CLACT PCI Current Limit Status
| Value | Description |
|---|---|
1 | PCI current limit output is active |
0 | PCI current limit output is inactive |
Bit 8 – FFACT PCI Feed-Forward Active Status
| Value | Description |
|---|---|
1 | PCI feed-forward output is active |

Bit 7 – TRSET PWM Generator Software Trigger Set
User software writes a ‘1’ to this bit location to trigger a
PWM Generator cycle. The bit location always reads as ‘0’. The TRIG
bit will indicate ‘1’ when the PWM Generator is triggered.
Bit 6 – TRCLR PWM Generator Software Trigger Clear
User software writes a ‘1’ to this bit location to stop a PWM
Generator cycle. The bit location always reads as ‘0’. The TRIG bit
will indicate ‘0’ when the PWM Generator is not triggered.
Bit 5 – CAP Capture Status
| Value | Description |
|---|---|
1 | PWM Generator time base value has been captured in PGxCAP |
0 | No capture has occurred |
Bit 4 – UPDATE PWM Data Register Update Status/Control
| Value | Description |
|---|---|
1 | PWM Data register update is pending – user Data registers are not writable |
0 | No PWM Data register update is pending |
Bit 3 – UPDREQ PWM Data Register Update Request
User software writes a ‘1’ to this bit location to request a
PWM Data register update. The bit location always reads as ‘0’. The
UPDATE status bit will indicate a ‘1’ when an update is pending.
Bit 2 – STEER Output Steering Status (Push-Pull Output mode only)
| Value | Description |
|---|---|
1 | PWM Generator is in 2nd cycle of Push-Pull mode |
0 | PWM Generator is in 1st cycle of Push-Pull mode |
Bit 1 – CAHALF Half Cycle Status (Center-Aligned modes only)
| Value | Description |
|---|---|
1 | PWM Generator is in 2nd half of time base cycle |
0 | PWM Generator is in 1st half of time base cycle |
Bit 0 – TRIG Trigger Status
| Value | Description |
|---|---|
1 | PWM Generator is triggered and PWM cycle is in progress |
0 | No PWM cycle is in progress |
