* @brief Number of bit-periods to hold the data line low at the end of a frame

- * The reset period for each frame must be at least 50 uS; so we add in 50 bit-times
- * of zeroes at the end. (50 bits)*(1.25 uS/bit) = 62.5 uS, which gives us some
- * slack in the timing requirements
+ * The reset period for each frame is defined in WS2812_TRST_US.
