7.4.3 Cautions on Channel Output Operation
278
(1) Changing values set in registers TOm,TOEm,TOLm, and TOMm during timer operation
(2) Default level of TOmn pin and output level after timer operation start
Remark
(a) When operation starts with TOMmn = 0 setting (toggle output)
Since the timer operations (operations of TCRmn and TDRmn) are independent of the TOmn output circuit
and changing the values set in TOm, TOEm, TOLm, and TOMm does not affect the timer operation, the values
can be changed during timer operation. To output an expected waveform from the TOmn pin by timer
operation, however, set TOm, TOEm, TOLm, and TOMm to the values stated in the register setting example of
each operation.
When the values set in TOEm, TOLm, and TOMm (except for TOm) are changed close to the timer interrupt
(INTTMmn), the waveform output to the TOmn pin may be different depending on whether the values are
changed immediately before or immediately after the timer interrupt (INTTMmn) signal generation timing.
The following figure shows the TOmn pin output level transition when writing has been done in the state of
TOEmn = 0 before port output is enabled and TOEmn = 1 is set after changing the default level.
Remarks 1. Toggle:
The setting of TOLmn is invalid when TOMmn = 0. When the timer operation starts after setting the default
level, the toggle signal is generated and the output level of TOmn pin is reversed.
(Same output waveform as TOLmn = 0)
(Same output waveform as TOLmn = 0)
m: Unit number (m = 0, 1), n: Channel number (n = 0 to 7),
mn = 00 to 07, 10 to 13
2. m: Unit number (m = 0, 1), n: Channel number (n = 0 to 7),
mn = 00 to 07, 10 to 13
Default level, TOLmn setting
