Timers
3.9.2.3 FTM external clock options
By default, each FTM is clocked by the chip's system clock (the FTM itself also refers to
it as the system clock). Each module has a register setting that allows the module to be
clocked from an external clock instead. There are two external TMR_CLKINx pins that
can be selected by either FTM module via the SOPT5 register in the SIM module.
3.9.3 Modulo Timer (MTIM) Configuration
This section summarizes how the module has been configured in the chip. For a
comprehensive description of the module itself, see the module’s dedicated chapter.
3.9.3.1 MTIM overview
The MTIM is a simple 16-bit modulo timer with several software selectable clock
sources and a programmable interrupt. The chip has one MTIM module.
The MTIM shares the TMR_CLKINx pins with the FlexTimer modules.
