3.9.2.2 FTM instantiation information
The chip contains two FlexTimer modules. The following table shows how these
modules are configured.
FTM0 and FTM1 have four fault inputs. The output of the CMP is connected to the fault
input 3 of both FTM0 and FTM1.
The 2-channel FTM0 pins are available only on the 64-pin packages of the chip.
Although 1 channel is available on 44-pin and 48-pin packages and neither of the FTM0
pins is available on 32-pin packages, they remain available for software timer functions
and internal connections from the CMP OUT.
The CMP OUT is connected to FTM0 Channel 0 to facilitate motor control applications.
Several FTM signals are and can be routed to multiple pins. For details about these pins
and about programming port mux control registers to assign an FTM function to those
pins, refer to
