s Notes on programmable generation waveform mode
Count set value
In the programmable waveform generation mode, values of TYS,
EXPYP, and EXPYS are valid by writing to TYP because the set-
ting to them is executed all at once by writing to TYP. Even when
changing TYP is not required, write the same value again.
Write timing to TYP
In the programmable waveform generation mode, when the set-
ting value is changed while the waveform is output, set by
software in order not to execute the writing to TYP and the timing
of timer underflow during the secondary interval simultanesously.
Usage of waveform extension function
The waveform extension function by the timer Y waveform exten-
sion control bit can be used only when “0016” is set to Prescaler Y.
When the value other than “0016” is set to Prescaler Y, be sure to
set “0” to EXPYP and EXPYS.
Timer Y write mode
When using this mode, be sure to set “1” to the timer Y write con-
trol bit to select “write to latch only”.
Timer Y can stop counting by setting “1” to the timer Y count stop
bit in any mode.
Also, when Timer Y underflows, the timer Y interrupt request bit is
set to “1”.
Timer Y reloads the value of latch when counting is stopped by the
timer Y count stop bit. (When timer is read out while timer is
stopped, the value of latch is read. The value of timer can be read
out only while timer is operating.)
