/*
The _delay_us function uses loops to generate an approximate delay for the specified number of microseconds.
It calculates the number of clock cycles required to achieve the requested delay and loops the corresponding number of times.
The temporal precision of _delay_us depends on the microcontroller's clock frequency (F_CPU).
For the ATmega328 operating at a typical frequency of 16 MHz, here are some details on the precision.
Clock Frequency: F_CPU must be defined correctly before using the function. For an ATmega328 operating at 16 MHz:
1 clock cycle = 1 / 16,000,000 s ≈ 62.5 ns
1 µs ≈ 16 clock cycles
BIT_OFFSET _delay_us(2.75) = 44 clock cycles
OVERRIDE _delay_us(0.2) = 3,2 clock cycles
