11.1.3
The block diagram for the modulo timer module is shown
11.2
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.
11.3
Each MTIM includes four registers, which are summarized in
Refer to the direct-page register summary in the memory section of this data sheet for the absolute address
assignments for all MTIM registers. This section refers to registers and control bits only by their names.
