The above link says, the maximal possible delay for _delay_us() is 768 us / F_CPU in MHz. However, as per the below computation, it should be 765us. (Max value of _ticks when it is of uint8_t type is 255.) _ticks = (F_CPU /3e^6)* _us => _us = 765/F_CPU in MHz Also, any reason why _ticks is chosen to be uint8_t type (but not uint16_t or uint32_t)?
