-- Added typedef T55xx_Timing to hold downlink timings.
-- Added Timing Records for long leading reference (llr), Leading 0 and 1 of 4
-- Added some constant defines for code readability
-- Added function T55xx_SetBits to build a bit stream for writing to T55xx
-- Added function T55xx_SendCMD to build the bit stream and send to T55xx
-
-### Changed
-- Converted Timing for default/fixed bit to T55xx_Timing
-- Updated T55xxWriteBit (and calls) to support all downlink protocols
-- Updated T55xxWriteBlock to call T55xx_SendCMD (removed local bit writes)
-- Updated T55xxReadBlock to call T55xx_SendCMD (removed local bit writes)
