10.8 TOU (Output-Related 24-Bit Timer)

MULTIJUNCTION TIMERS

10.8.14 Operation in TOU PWM Output Mode (without Correction Function)

(1) Outline of TOU PWM output mode

In PWM output mode, the timer uses two reload registers to generate a waveform with a given duty

cycle.When PWM output mode, it is operated as a 16 bit timer.

When the timer is enabled after setting the initial values in the reload 0 and reload 1 registers, the counter is

loaded with the value that " the reload 0 register -1" and starts counting down synchronously with the count

clock at the next cycle. The next cycle after the first time the counter underflows, it is loaded with the value

that " the reload 1 register -1" and continues counting. Thereafter, the counter is loaded with the reload 0

and reload 1 register values alternately each time an underflow occurs. The " reload 0 register set value + 1"

and " reload 1 register set value + 1" respectively are effective as count values. The timer stops at the same

time count is disabled by writing to the enable bit (and not in synchronism with PWM output period).

The F/F output waveform in PWM output mode is inverted (F/F output level changes from "L" to "H" or vice

versa) when the counter starts counting and each time it underflows. An interrupt request and DMA transfer

request can be generated at even-numbered occurrences of underflow after the counter is enabled.

If the value "H'FFFF" is set in either the reload 0 register or the reload 1 register, F/F output will not be

inverted although an interrupt request is generated upon underflow, making it possible to produce a 0% or

100% duty-cycle PWM output. Because a 0% or 100% duty-cycle needs to be determined when reloading

the counter, there is a one count clock equivalent delay before F/F is inverted and an interrupt or DMA

transfer request is generated. However, startup requests to other timers are not delayed. For details, see

Section 10.8.19, “0% or 100% Duty-Cycle Wave Output during PWM Output and Single-shot PWM Output

Note that TOU’s PWM output mode does not have the count correction function.
