20.2 Carrier Frequency
The carrier frequency and the pulse of data are calculated
by below formula. The the lengths of carrier frequency and
pulse of data are shown in Figure 20-3.
t_H = source clock(RMR[5:4]) × CFHS
t_L = source clock(RMR[5:4]) × CFHS
f_C (Carrier Frequency) = 1/(t_H+t_L)
t_DH = source clock(RMR[2:0]) × RDHR
t_DL = source clock(RMR[2:0]) × RDLR
