Output Compare
In this section, the index, i, may be 1 or 2 because there are two output compare functions in
the 16-bit timer.
This function can be used to control an output waveform or indicate when a period of time
has elapsed.
When a match is found between the output Compare register and the free running counter,
the output compare function:
●
●
●
Two 16-bit registers output Compare register 1 (OC1R) and output Compare register 2
(OC2R) contain the value to be compared to the counter register each timer clock cycle.
Table 20.
These registers are readable and writable and are not affected by the timer hardware. A
reset event changes the OC
Timing resolution is one count of the free running counter: (
Procedure
To use the output compare function, select the following in the CR2 register:

Assigns pins with a programmable value if the OCiE bit is set
Sets a flag in the status register
Generates an interrupt if enabled
Set the OCiE bit if an output is needed then the OCMPi pin is dedicated to the output
compare i signal.
Select the timer clock (CC[1:0]) (see
Select the following in the CR1 register:

b)
OCFi bit is set.
The OCMPi pin takes OLVLi bit value (OCMPi pin latch is forced low during reset).
A timer interrupt is generated if the OCIE bit is set in the CR1 register and the I bit is
cleared in the CC register (CC).
