1. Interrupts may be lost when writing the timer registers in the asynchronous
Interrupts may be lost when writing the timer registers in the asynchronous timer
timer
The interrupt will be lost if a timer register that is synchronous timer clock is written
when the asynchronous Timer/Counter register (TCNTx) is 0x00.
Always check that the asynchronous Timer/Counter register neither have the value
0xFF nor 0x00 before writing to the asynchronous Timer Control Register (TCCRx),
asynchronous Timer Counter Register (TCNTx), or asynchronous Output Compare
Register (OCRx).
