10.6 Data mapping for VPPM
VPPM waveforms are shown in Figure xx. The data mapping for VPPM shall be defined as in Table xx. The physical value mapped from the logical data ‘0’ has a transition from ‘high’ to ‘low’, and the physical value mapped from the logical data ‘1’ has a transition from ‘low’ to ‘high’, as stated in Table xx and shown in Figure xx. ‘Low’ and ‘high’ values are defined in 8.3.2.The variable n in Table xx is the dimming level. If the ‘low’ level translates into the absence of transmission and the amplitude of the ‘high’ level is fixed, dimming is supported in dimming steps of 0.1% between 10% and 90% (corresponding to n = 100, …, 900). Figure xx shows the examples of the VPPM waveform for dimming levels n = 100, 400, and 700, respectively.

Get source file from Dr. Lim and replace the above table. Ask Dr. Lim to translate it into a monochrome table.

11.4 Data mapping for VPPM
All PHY II VPPM modes shall use data mapping as defined in 10.6.
