Compare Output Mode

To select this mode, bits TnAM1, TnAM0 and TnBM1, TnBM0 in the TMnC1/TMnC2 registers

should be all cleared to zero. 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 TnCCLR bit is low, there are two ways in which the counter can

be cleared. One is when a compare match occurs from Comparator P, the other is when the CCRP bits

are all zero which allows the counter to overflow. Here both the TnAF and TnPF interrupt request flags

for Comparator A and Comparator P respectively, will both be generated.

If the TnCCLR bit in the TMnC1 register is high then the counter will be cleared when a compare

match occurs from Comparator A. However, here only the TnAF interrupt request flag will be

generated even if the value of the CCRP bits is less than that of the CCRA registers. Therefore when

TnCCLR is high no TnPF interrupt request flag will be generated.

ETM CCRA Compare Match Output Mode -- TnCCLR = 0

Note:

1. With TnCCLR=0 a Comparator P match will clear the counter

2. The TPnA output pin is controlled only by the TnAF flag

3. The output pin is reset to its initial state by a TnON bit rising edge
