FL_OPTIMIZE_FUNCTION FL_IRAM FASTLED_FORCE_INLINE void fl::isr::memset_zero_word	(	u8 *	dest,
		size_t	count )

ISR-safe word-aligned memset (4-byte writes)

Parameters

dest	Destination pointer (must be 4-byte aligned)
count	Number of bytes to zero (will process in 4-byte chunks)

Note

Handles remainder bytes using byte writes
