11.12.1 Conflict between Write to TLR and Count Up/Automatic Reload
Even if a count up occurs in the T2 state during TLR write cycles, the counter is not incremented
and TLR write (load to TCNT) is carried out instead (as in Figure 11.11).
Likewise, if an automatic reload occurs during write cycles, TLR write (load to TCNT) is carried
out instead.
11.12.2 Switchover of Internal Clock and TCNT Operation
Depending on the timing which the internal clock is switched, TCNT may be incremented (see
table 11.4). Likewise, when the clock pulse is changed (φ and φ
and may not in some cases. Therefore, when the internal clock is changed, resume timer operation
by resetting TLR (Write H'00 to TLR when the interval timer is in operation).
11.12.3 Interrupt during Module Stop
When module stop mode is entered with an interrupt being requested, the cause of an interrupt to
the CPU cannot be cleared. Enter module stop mode after, for example, disabling an interrupt
request.
Although the automatic reload function is usually set and implemented in individual channel, a
cascaded channel operates according to the setting for the automatic reload function of the
highest channel.
In this case, the automatic reload function settings for the channels other than the highest
channel are disabled. When the automatic reload function is enabled for cascaded channel, the
TLR setting value of each channel is automatically reloaded simultaneously in the reload
timing of the highest channel.
Although an OVF is usually set to an individual channel independently, an OVF is set to the
highest channel of a cascaded channel. In this case, OVFs of the channels other than that of the
highest channel is disabled.
