36.4 Functional Description
The following sections describe the FTM features.
The notation used in this document to represent the counters and the generation of the
signals is shown in the following figure.
36.4.1 Clock Source
FTM module has only one clock domain that is the system clock.
36.4.1.1 Counter Clock Source
The CLKS[1:0] bits in the SC register select one of three possible clock sources for the
FTM counter or disable the FTM counter. After any MCU reset, CLKS[1:0] = 0:0 so no
clock source is selected.
The CLKS[1:0] bits may be read or written at any time. Disabling the FTM counter by
writing 0:0 to the CLKS[1:0] bits does not affect the FTM counter value or other
registers.
