clock frequency varies with each product, and so the value set in the SysTick Calibration Value Register also varies
with each product.
Non-Maskable Interrupts (NMI)
SysTick
Non-maskable interrupts are generated from the following two sources.
Use the NMI Flag (CGNMIFLG) Register of the clock generator to identify the source of a non-maskable interrupt.
SysTick provides interrupt features using the CPU's system timer.
When you set a value in the SysTick Reload Value Register and enable the SysTick features in the SysTick Control
The SysTick Calibration Value Register holds a reload value for counting 10 ms with the system timer. The count
Note:In this product, the system timer counts based on a clock obtained by dividing the clock input from the

the clock input from X1 is 8 MHz.
on the WDT.
A non-maskable interrupt is generated when an external NMI pin changes from "High" to "Low".
The watchdog timer (WDT) has a non-maskable interrupt generating feature. For details, see the chapter
