6.7 Operation of Timer Array Unit as Independent Channel
6.7.1 Operation as interval timer/square wave output
(1) Interval timer
(2) Operation as square wave output
The timer array unit can be used as a reference timer that generates INTTM0n (timer interrupt) at fixed
intervals.
The interrupt generation period can be calculated by the following expression.
A subsystem clock divided by four (f
Consequently, the interval timer can be operated with the count clock fixed to f
frequency (main system clock, subsystem clock). When changing the clock selected as f
value of the system clock control register (CKC)), however, stop the timer array unit (TAU) (TT0 = 00FFH) first.
TO0k performs a toggle operation as soon as INTTM0n has been generated, and outputs a square wave with a
duty factor of 50%.
The period and frequency for outputting a square wave from TO0k can be calculated by the following
expressions.
TCR0n operates as a down counter in the interval timer mode.
TCR0n loads the value of TDR0n at the first count clock after the channel start trigger bit (TS0n) is set to 1. If
MD0n0 of TMR0n = 0 at this time, INTTM0n is not output and TO0k is not toggled. If MD0n0 of TMR0n = 1,
INTTM0n is output and TO0k is toggled.
After that, TCR0n count down in synchronization with the count clock.
When TCR0n = 0000H, INTTM0n is output and TO0k is toggled at the next count clock. At the same time,
TCR0n loads the value of TDR0n again. After that, the same operation is repeated.
TDR0n can be rewritten at any time. The new value of TDR0n becomes valid from the next period.
Remarks 1. n = 0 to 7, k = 0 to 6
Generation period of INTTM0n (timer interrupt) = Period of count clock × (Set value of TDR0n + 1)
• Period of square wave output from TO0k = Period of count clock × (Set value of TDR0n + 1) × 2
• Frequency of square wave output from TO0k = Frequency of count clock/{(Set value of TDR0n + 1) × 2}
