2. Time-Base Timer
Interval time of time-base timer
2/HCLK (0.5 s)
Interval timer function
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.
• When the counter of time-base timer reaches an interval time specified by interval time selection bit
• If an interrupt by overflow is permitted (TBTC: TBIE=1), an interrupt is generated when overflow occurs (TBTC:
• The following four interval time settings are selectable :
HCLK: Oscillation clock
Values in parentheses “( )” are those under operation of 4-MHz oscillation clock.
(TBTC:TBC1, TBC0), an overflow (carrying-over) occurs (TBTC: TBOF=1) and interrupt request is generated.
