17.5.1.2 4.0 Mbps FIR Frame Format
Receive data sample counter frequency = 6x pulse width, each time-slot sampled on third clock.
When the 4.0 Mbps transmission rate is used, the high-speed serial/parallel (FIR) interface
within the FIR is used along with the 4PPM bit encoding. The high-speed frame format shown
in
flags and CRC are twice as long and instead of one start flag, a preamble and start flag of
differing length are used.
