Modulo Timer (S08MTIMV1)
13.1.4
The block diagram for the modulo timer module is shown
13.2
The MTIM includes one external signal, TCLK, used to input an external clock when selected as the
MTIM clock source. The signal properties of TCLK are shown in
The TCLK input must be synchronized by the bus clock. Also, variations in duty cycle and clock jitter
must be accommodated. Therefore, the TCLK signal must be limited to one-fourth of the bus frequency.
The TCLK pin can be muxed with a general-purpose port pin. See the
the pin location and priority of this function.
