Chapter 22 Main Oscillation Stabilisation Timer
7.Q & A
7.6 What are the types of interrupt?
There is one type of interrupt called the main clock oscillation stability wait timer interrupt.
(Selection is unnecessary.)
7.7 how is an interrupt enabled?
Interrupt request enable and interrupt request flag
Setting the interrupt enable is performed with the interrupt request enable bit (OSCRH.WIE).
Clearing an interrupt request is performed with the interrupt request bit (OSCRH.WIF).
7.8 How is the main clock oscillation stability wait timer stopped counting?
Sets with the timer operation enable bit (OSCRH.WEN). Refer to 7.3.
In addition, if the MCU stops the main clock while the subclock is being operated, the main clock oscillation
stability wait timer also stops counting.
Interrupt request enable bit (WIE)
Interrupt disable Set the value to “0”
Interrupt enable Set the value to “1”
Interrupt request bit (WIF)
Interrupt request clear Writes “0”
