Figure 51 Timer C Block Diagram
Timer C Operations:
Free-running/reload timer operation: The free-running/reload operation, input clock source, and
prescaler division ratio are selected by timer mode register C1 (TMC1: $00D).
Timer C is initialized to the value set in timer write register C (TWCL: $00E, TWCU: $00F) by
software and incremented by one at each clock input. If an input clock is applied to timer C after it has
reached $FF, an overflow is generated. In this case, if the reload timer function is enabled, timer C is
initialized to its initial value set in timer write register C; if the free-running timer function is enabled,
the timer is initialized to $00 and then incremented again.
