STATEx bit. For further details on timer/counter commands, refer to available commands description
(31.8.3 CTRLBSET.CMD).
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 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 (FAULTB.HALT=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 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 (FAULTA.HALT=SW), clearing
this bit will release the timer/counter.
Bit 11 – FAULT1IN Non-Recoverable Fault 1 Input
This bit is set while an active Non-Recoverable Fault 1 input is present.
Bit 10 – FAULT0IN Non-Recoverable Fault 0 Input
This bit is set while an active Non-Recoverable Fault 0 input is present.
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
This bit is set while an active Recoverable Fault A input is present.
Bit 7 – PERBV Period Buffer Valid
This bit is set when a new value is written to the PERB register. This bit is automatically cleared by
hardware on UPDATE condition when CTRLB.LUPD is set, or by writing a '1' to this bit.
Bit 6 – WAVEBV Waveform Control Buffer Valid
This bit is set when a new value is written to the WAVEB register. This bit is automatically cleared by
hardware on UPDATE condition when CTRLB.LUPD is set, or by writing a '1' to this bit.
Bit 5 – PATTBV Pattern Generator Value Buffer Valid
This bit is set when a new value is written to the PATTB register. This bit is automatically cleared by
hardware on UPDATE condition when CTRLB.LUPD is set, or by writing a '1' to this bit.
Bit 3 – DFS Debug Fault State
This bit is set by hardware in debug mode when DDBGCTRL.FDDBD 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.NRE and
DRVCTRL.NRV 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). The bit is cleared by writing a one to this bit.
