Equation B.18
Set Group 4, APR 33 to 0x2B and APR 32 to 0x8E.
Group 4, APR 34–35 – Set to 0x3334.
The value for the upper sweep limit, CAR_USWL[15:0], is set as
explained in the following paragraphs. It should be noted that the upper
sweep limit is an approximate value but the approximation to the real
sweep limit is accurate enough. Assume that the upper sweep limit
needed is + 5 MHz. The maximum sweep limit achievable is
Calculate CAR_USWL[15:0] as shown in
B.20.

Set Group 4 APR 35 to 0x19 and APR 34 to 0x9A.
Group 4, APR 36–37 – Set to 0xCCCC.
The value for the lower sweep limit, CAR_LSWL[15:0], is set as
explained in the following paragraphs. It should be noted that the lower
sweep limit is an approximate value but the approximation to the real
sweep limit is accurate enough. Assume that the lower sweep limit
needed is
