5.10 Timer Controller (TMR)
5.10.1 Overview
5.10.2 Features
The timer controller includes four 32-bit timers, TIMER0~TIMER3, which allows user to easily
implement a timer control for applications. The timer can perform functions like frequency
measurement, event counting, interval measurement, clock generation, delay timing, and so on.
The timer can generates an interrupt signal upon timeout, or provide the current value during
operation. Note: event counting function only support in NuMicro™ NUC100 Low Density.
4 sets of 32-bit timers with 24-bit up-timer and one 8-bit pre-scale counter
Independent clock source for each timer
Provides one-shot, periodic, toggle and auto-reload counting operation modes
Time out period = (Period of timer clock input) * (8-bit pre-scale counter + 1) * (24-bit TCMP)
Maximum counting cycle time = (1 / 25 MHz) * (2^8) * (2^24), if timer clock is 25 MHz
24-bit timer value is readable through TDR (Timer Data Register)
