<Notes on Timer X>
(1) Write Order to Timer X
In the timer mode, pulse output mode, event counter mode and
pulse width measurement mode, write to the following
registers in the order as shown below;
the timer X register (extension),
the timer X register (low-order),
the timer X register (high-order).
Do not write to only one of them.
When the above mode is set and timer X operates as the 16-bit
counter, if the timer X register (extension) is never set after
reset is released, setting the timer X register (extension) is not
required. In this case, write the timer X register (low-order)
first and the timer X register (high-order). However, once
writing to the timer X register (extension) is executed, note that
the value is retained to the reload latch.
Write to the timer X register by the 16-bit unit. Do not read the
timer X register while write operation is performed. If the
write operation is not completed, normal operation will not be
performed.
In the IGBT output and PWM modes, do not write “1” to the
timer X register (extension). Also, when “1” is already written
to the timer X register, be sure to write “0” to the register
before using.
Write to the following registers in the order as shown below;
the compare registers 1, 2, 3 (high- and low-order),
the timer X register (extension),
the timer X register (low-order),
the timer X register (high-order).
It is possible to use whichever order to write to the compare
registers 1, 2, 3 (high- and low-order). However, write both the
compare registers 1, 2, 3 and the timer X register at the same
time.
For the compare registers, set a value less than the setting value
in the timer X register. Also, do not set “00
16
”.
(2) Read Order to Timer X
In all modes, read the following registers in the order as shown
below;
the timer X register (extension),
the timer X register (high-order),
the timer X register (low-order).
When reading the timer X register (extension) is not required,
read the timer X register (high-order) first and the timer X
register (low-order).
Read order to the compare registers 1, 2, 3 is not specified.
Read from the timer X register by the 16-bit unit. Do not write
to the timer X register while read operation is performed. If the
read operation is not completed, normal operation will not be
performed.
(3) Write to Timer X
Which write control can be selected by the timer X write
control bit (b3) of the timer X mode register (address 2D
16
),
writing data to both the latch and the timer at the same time or
writing data only to the latch. When writing a value to the
timer X address to write to the latch only, the value is set into
the reload latch and the timer is updated at the next underflow.
After reset release, when writing a value to the timer X
address, the value is set into the timer and the timer latch at the
same time, because they are written at the same time.
When writing to the latch only, if the write timing to the high-
order reload latch and the underflow timing are almost the
same, the value is set into the timer and the timer latch at the
same time. In this time, counting is stopped during writing to
the high-order reload latch.
Switch the frequency division or count source* while the timer
count is stopped.
*This also applies when the frequency divider output is selected
as the timer count source and the count source is switched in
conjunction with a transition between operating modes (on-
chip oscillator mode, X
IN
mode, or low-speed mode). Be
careful when changing settings in the CPU mode register.
