sTimer mode
Figure 2.3.28 shows an example of setting registers for using the timer mode.
[Notes on use]
Notes 1: For using interrupt processing, set the following :
•Before setting Œ below, clear the timer Y interrupt enable bit and the timer Y
interrupt request bit to “0.”
•After setting  below, set the timer Y interrupt enable bit to “1” (interrupts enabled) .
2: Write values in the order of the timer Y (low-order) and the timer Y (high-order).

: Nothing is allocated
Set count value (low-order) to timer Y (low-order) (TYL) [Address 2216]
ŽSet count value (high-order) to timer Y (high-order) (TYH) [Address 2316]
Set timer Y stop control bit of timer Y mode register to “0” to start counting
