Set the carrier signal H section length. (Default: 0x0)
Specify a value corresponding to the number of carrier generation clock cycles selected by CG-
CLK[3:0] (D[7:4]/REMC_PSC register) + 1.
Calculate carrier H section length as follows:
Carrier H section length = —————— [s]
REMCH: REMCH[5:0] settings
clk_in:
The L section length is specified by REMCL[5:0] (D[5:0]/REMC_CARL register).
The carrier signal is generated from these settings as shown in Figure 21.7.1.
Example: CGCLK[3:0] = 0x2 (PCLK-1/4), REMCH[5:0] = 2, REMCL[5:0] = 1
