1. For bus frequencies less than 1MHz, the internal RC oscillator should be used when programming the EEPROM.
2. Since the 2-bit prescaler in the timer must count four external cycles (tCYC), this is the limiting factor in determining the
timer resolution.
3. The minimum period tTLTL should not be less than the number of cycles it takes to execute the capture interrupt service
routine plus 24 tCYC.
4. The minimum period tILIL should not be less than the number of cycles it takes to execute the interrupt service routine plus
21 tCYC.
