M24LR16E-R to VCD frames
Frames are delimited by an SOF and an EOF. They are implemented using code violation.
Unused options are reserved for future use. For the low data rate, the same subcarrier
frequency or frequencies is/are used. In this case, the number of pulses is multiplied by 4.
For the Fast commands using one subcarrier, all pulse numbers and times are divided by 2.
