Wait for time by polling (specified in μsec).
voiddelayMicroseconds(uint32_t microsec)
Wait for a given period of time in microsec.
The time is measured by the TickTimer count. When waiting for a long time, the CPU clock is reduced and polling is performed.
In the setup(), wakeup() function, TickTimer is not yet running, so it waits for a while in a while loop. In this case, the error with the specified value will be large. This loop counter is adjusted to 32Mhz. If the CPU clock is changed in these functions, the error will be proportional to the clock.
If you specify a short time, such as less than 10 for a parameter, the error may be large.
