*
* OSv1 protocol.
*
* MC with nominal bit width of 2930 us.
* Pulses are somewhat longer than nominal half-bit width, 1748 us / 3216 us,
* Gaps are somewhat shorter than nominal half-bit width, 1176 us / 2640 us.
* After 12 preamble bits there is 4200 us gap, 5780 us pulse, 5200 us gap.
* And next 32 bit data
*
* Care must be taken with the gap after the sync pulse since it
* is outside of the normal clocking. Because of this a data stream
* beginning with a 0 will have data in this gap.
*
*
* Data is in reverse order of bits
* RevBit(data32bit)=> tib23atad
*
* tib23atad => xxxxxxxx | busuTTTT | ttttzzzz | ccuuiiii
