Time-Base Timer
The time-base time is an 18-bit free-run counter (time-base timer counter) that counts up in synchronization with
the main clock (dividing main oscillation clock by 2).
Four choices of interval time are selectable, and generation of interrupt request is allowed for each interval time.
Provides operation clock signal to oscillation stabilizing wait timer and peripheral functions.
Interval timer function
When the counter of time-base timer reaches an interval time specified by interval time selection bit
(TBTC:TBC1, TBC0), an overflow (carrying-over) occurs (TBTC: TBOF=1) and interrupt request is generated.
If an interrupt by overflow is permitted (TBTC: TBIE=1), an interrupt is generated when overflow occurs (TBTC:
TBOF=1).
The following four interval time settings are selectable :
Interval time of time-base timer
HCLK: Oscillation clock
Values in parentheses “( )” are those under operation of 4-MHz oscillation clock.
Count clock
Interval time
2/HCLK (0.5
s)
212/HCLK (Approx. 1.0 ms)
214/HCLK (Approx. 4.1 ms)
216/HCLK (Approx. 16.4 ms)
219/HCLK (Approx. 131.1 ms)
