Bits 31:24 – CMP[7:0] Compare Channel x Value
Bits 23:16 – CCBUFV[7:0] Compare Channel x Buffer Valid
Bit 15 – FAULT1 Non-Recoverable Fault 1 State
This bit is set by hardware as soon as non-recoverable Fault 1 condition occurs.
This bit is cleared by writing a one to this bit and when the corresponding STATUS.FAULT1IN(STATUS<11>) status bit is low.
Once this bit is cleared, the TCC will restart from the last COUNT value. To restart the TCC from BOTTOM, the TCC restart (RETRIGGER) command (CTRLBSET.CMD (CTRLBSET<7:5>)=1) must be executed before clearing the FAULT1 STATE bit. For further details on TCC commands, refer to the available commands description in the CTRLBSET register.
Bit 14 – FAULT0 Non-Recoverable Fault 0 State
This bit is set by hardware as soon as non-recoverable Fault 0 condition occurs.
This bit is cleared by writing a one to this bit and when the corresponding STATUS.FAULT0IN(STATUS<10>) status bit is low.
Once this bit is cleared, the TCC will restart from the last COUNT value. To restart the TCC from BOTTOM, the TCC restart (RETRIGGER) command (CTRLBSET.CMD (CTRLBSET<7:5>)=1) must be executed before clearing the FAULT0 STATE bit. For further details on TCC commands, refer to the available commands description in the CTRLBSET register.
Bit 13 – FAULTB Recoverable Fault B State
This bit is set by hardware as soon as recoverable Fault B condition occurs.
This bit can be clear by the hardware when Fault B action is resumed, or by writing a '1' to this bit when the corresponding FAULTBIN bit is low. If software halt command is enabled (FCTRLB.HALT (FCTRLB<9:8>) =SW), clearing this bit will release the timer/counter.
Bit 12 – FAULTA Recoverable Fault A State
This bit is set by hardware as soon as recoverable Fault A condition occurs.
This bit can be clear by the hardware when Fault A action is resumed, or by writing a '1' to this bit when the corresponding FAULTAIN bit is low. If software halt command is enabled (FCTRLA.HALT (FCTRLB<9:8>) =SW), clearing this bit will release the timer/counter.
Bit 11 – FAULT1IN Non-Recoverable Fault1 Input
This bit is set while an active Non-Recoverable Fault 1 input is present.
Bit 10 – FAULT0IN Non-Recoverable Fault0 Input
Bit 9 – FAULTBIN Recoverable Fault B Input
This bit is set while an active Recoverable Fault B input is present.
Bit 8 – FAULTAIN Recoverable Fault A Input
Bit 7 – PERBUFV Period Buffer Valid
This bit is set when a new value is written to the PERBUF register. The bit is cleared either by writing a '1' to the corresponding location when CTRLBSET.LUPD (CTRLBSET<1>) is set, or automatically on an UPDATE condition.
Bit 5 – PATTBUFV Pattern Buffer Valid
Bit 4 – SLAVE Slave
Bit 3 – DFS Non-Recoverable Debug Fault State
This bit is set by hardware in Debug mode when DDBGCTRL.FDDBD(DDBGCTRL<2>) bit is set. The bit is cleared by writing a '1' to this bit and when the TCC is not in Debug mode.
When the bit is set, the counter is halted and the Waveforms state depend on DRVCTRL.NREy and DRVCTRL.NRVy registers.
Bit 2 – UFS Non-recoverable Update Fault State
This bit is set by hardware when the Ramp index changes and the Lock Update bit is set (CTRLBSET.LUPD (CTRLBSET<1>)). The bit is cleared by writing a one to this bit.
When the bit is set, the waveforms state depend on DRVCTRL.NREy and DRVCTRL.NRVy registers.
Bit 1 – IDX Ramp
In RAMP2 and RAMP2A operation, the bit is cleared during the cycle A and set during the cycle B. In RAMP1 operation, the bit always reads zero. For details on Ramp operations, refer to the .
Bit 0 – STOP Stop
This bit is set when the TCC is disabled either on a STOP command or on an UPDATE condition when One-Shot operation mode is enabled (CTRLBSET.ONESHOT(CTRLBSET <2>)=1).
This bit is clear on the next incoming counter increment or decrement.
| Value | Description |
|---|---|
| 0 | Counter is running. |
| 1 | Counter is stopped. |
