Access:
• WRDY: Write Ready for Synchronous Channels Update
0 = New duty-cycle and dead-time values for the synchronous channels cannot be written.
1 = New duty-cycle and dead-time values for the synchronous channels can be written.
• ENDTX: PDC End of TX Buffer
0 = The Transmit Counter register has not reached 0 since the last write of the PDC.
1 = The Transmit Counter register has reached 0 since the last write of the PDC.
• TXBUFE: PDC TX Buffer Empty
0 = PWM_TCR or PWM_TCNR has a value other than 0.
1 = Both PWM_TCR and PWM_TCNR have a value other than 0.
• UNRE: Synchronous Channels Update Underrun Error
0 = No Synchronous Channels Update Underrun has occurred since the last read of the PWM_ISR2 register.
1 = At least one Synchronous Channels Update Underrun has occurred since the last read of the PWM_ISR2 register.
• CMPMx: Comparison x Match
0 = The comparison x has not matched since the last read of the PWM_ISR2 register.
1 = The comparison x has matched at least one time since the last read of the PWM_ISR2 register.
• CMPUx: Comparison x Update
0 = The comparison x has not been updated since the last read of the PWM_ISR2 register.
1 = The comparison x has been updated at least one time since the last read of the PWM_ISR2 register.
