Bit 0

 PTCCLR

: PTM 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 

Periodic TM contains two comparators, Comparator A and Comparator P, either of 

which can be selected to clear the internal counter. With the PTCCLR 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 PTCCLR bit is not 

used in the PWM Output, Single Pulse Output or Capture Input Mode.

Periodic Type TM Operation Modes

The Periodic Type TM can operate in one of five operating modes, Compare Match Output Mode, 
PWM Output Mode, Single Pulse Output Mode, Capture Input Mode or Timer/Counter Mode. The 
operating mode is selected using the PTM1 and PTM0 bits in the PTMC1 register.

Compare Match Output Mode

To select this mode, bits PTM1 and PTM0 in the PTMC1 register, should be set to 00 respectively. 
In this mode once the counter is enabled and running it can be cleared by three methods. These are 
a counter overflow, a compare match from Comparator A and a compare match from Comparator P. 
When the PTCCLR bit is low, there are two ways in which the counter can be cleared. One is when 
a compare match from Comparator P, the other is when the CCRP bits are all zero which allows the 
counter to overflow. Here both PTMAF and PTMPF interrupt request flags for Comparator A and 
Comparator P respectively, will both be generated.
If the PTCCLR bit in the PTMC1 register is high then the counter will be cleared when a compare 
match occurs from Comparator A. However, here only the PTMAF interrupt request flag will be 
generated even if the value of the CCRP bits is less than that of the CCRA registers. Therefore when 
PTCCLR is high no PTMPF interrupt request flag will be generated. In the Compare Match Output 
Mode, the CCRA can not be set to “0”.
As the name of the mode suggests, after a comparison is made, the PTM output pin will change 
state. The PTM output pin condition however only changes state when a PTMAF interrupt request 
flag is generated after a compare match occurs from Comparator A. The PTMPF interrupt request 
flag, generated from a compare match occurs from Comparator P, will have no effect on the PTM 
output pin. The way in which the PTM output pin changes state are determined by the condition of 
the PTIO1 and PTIO0 bits in the PTMC1 register. The PTM output pin can be selected using the 
PTIO1 and PTIO0 bits to go high, to go low or to toggle from its present condition when a compare 
match occurs from Comparator A. The initial condition of the PTM output pin, which is setup after 
the PTON bit changes from low to high, is setup using the PTOC bit. Note that if the PTIO1 and 
PTIO0 bits are zero then no pin change will take place.
