Description
Trigger for Counter=Comparator B Up
Value Description
1 An ADC trigger pulse is output when the counter matches the
value in the PWMnCMPB register value while counting up.
0 No ADC trigger is output.
0
Trigger for Counter=Comparator A Down
Value Description
1 An ADC trigger pulse is output when the counter matches the
value in the PWMnCMPA register value while counting down.
0 No ADC trigger is output.
0
Trigger for Counter=Comparator A Up
Value Description
1 An ADC trigger pulse is output when the counter matches the
value in the PWMnCMPA register value while counting up.
0 No ADC trigger is output.
0
Trigger for Counter=Load
Value Description
1 An ADC trigger pulse is output when the counter matches the
PWMnLOAD register.
0 No ADC trigger is output.
0
Trigger for Counter=0
Value Description
1 An ADC trigger pulse is output when the counter is 0.
0 No ADC trigger is output.
0x0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0
Interrupt for Counter=Comparator B Down
Value Description
1 A raw interrupt occurs when the counter matches the value in
the PWMnCMPB register value while counting down.
0 No interrupt.
