- Updated all input read macros (PIN_SQCK_READ, PIN_SUBQ_READ, etc.) to use double logical NOT (!!) operators. - This ensures bitwise masks are normalized to a pure 0 or 1 boolean value. - Optimization: Allows the compiler to use faster AVR branch instructions (SBIC/SBIS) and improves compatibility with direct equality tests. - Updated inline documentation for better clarity on bitwise operations.
