13.3
16-bit Free-run Timer
The 16-bit free-run timer consists of a 16-bit up counter and a control status register.
The count values of this timer are used as the base timer for the output compares and
input captures.
• Eight counter clock frequencies are available.
• An interrupt can be generated upon a counter value overflow.
• The counter value can be initialized upon a match with compare register 0 (free-run
timer 0) or compare register 4 (free-run timer 1), depending on the mode.
• Two separate timers are available on MB90390 series.
