New 2-phase sync (Stabilization + Silence detection). Refactored GPIO macros for faster execution. Cleaned up SCPH model definitions and fixed backslash warnings. Removed unused global variables to save RAM.

/*
|
|
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.
