Modulo Timer (RS08MTIMV1)
11.1
The MTIM is a simple 8-bit timer with several software selectable clock sources and a programmable
interrupt.
The central component of the MTIM is the 8-bit counter that can operate as a free-running counter or a
modulo counter. A timer overflow interrupt can be enabled to generate periodic interrupts for time-based
software loops.
The TCLK input is connected to the PTA2 pin of the MC9RS08KA2 Series. The XCLK input is connected
to the ICSFFCLK clock divided by two, where the ICSFFCLK is the fixed-frequency internal reference
clock from the ICS module.
