For a word connection, access in word units.
When writing to the cascaded TLR, even if a single channel of TLR is written, the system
regards that the entire channels of the cascaded TLR are rewritten. At this point in time, the
value in the entire cascaded TLR is loaded into the corresponding TCNT. The timer operation
starts at the TLR value that is most-recently written in TLR access cycles.
Although each channel usually operates on an individual clock, a cascaded channel operates on
the same clock. The operation clock for the lowest cascaded channel is used as a common
clock of each channel.
In this case, the setting for the clocks of the channels other than the lowest channel is disabled.
