Bit 3
STOC
: STM STP Output control
Compare Match Output Mode
0: Initial low
1: Initial high
PWM Output Mode/Single Pulse Output Mode
0: Active low
1: Active high
This is the output control bit for the STM output pin. Its operation depends upon
whether STM is being used in the Compare Match Output Mode or in the PWM
Mode/Single Pulse Output Mode. It has no effect if the STM is in the Timer/Counter
Mode. In the Compare Match Output Mode it determines the logic level of the STM
output pin before a compare match occurs. In the PWM Mode/Single Pulse Output
Mode it determines if the PWM signal is active high or active low.
Bit 2
STPOL
: STM STP Output polarity control
0: Non-inverted
1: Inverted
This bit controls the polarity of the STP output pin. When the bit is set high the STM
output pin will be inverted and not inverted when the bit is zero. It has no effect if the
STM is in the Timer/Counter Mode.
Bit 1
STDPX
: STM PWM duty/period control
0: CCRP – period; CCRA – duty
1: CCRP – duty; CCRA – period
This bit determines which of the CCRA and CCRP registers are used for period and
duty control of the PWM waveform.
Bit 0
STCCLR
: STM Counter Clear condition selection
0: Comparator P match
1: Comparator A match
This bit is used to select the method which clears the counter. Remember that the
Standard TM contains two comparators, Comparator A and Comparator P, either of
which can be selected to clear the internal counter. With the STCCLR bit set high,
the counter will be cleared when a compare match occurs from the Comparator A.
When the bit is low, the counter will be cleared when a compare match occurs from
the Comparator P or with a counter overflow. A counter overflow clearing method can
only be implemented if the CCRP bits are all cleared to zero. The STCCLR bit is not
used in the PWM Output, Single Pulse Output or Capture Input Mode.
