11-9 | Lane Setup/ARM PLL Setting | When Boot Master = 0 (ARM is Boot Master), pin[11:9] used as ARM PLL Setting. The PLL default settings are determined by the [11:9] bits. This will set the PLL to the maximum clock setting for the device. Table 10-27 shows settings for various input clock frequencies.
When Boot Master =1 (C66x is Boot Master), pin [10:9] are used as Lane Set up.

7-5 | SYS PLL Setting | The PLL default settings are determined by the [7:5] bits. This will set the PLL to the maximum clock setting for the device. Default system reference clock is 156.25 MHz. Table 10-27 shows settings for various input clock frequencies. (default = 4) |
4 | Min | Minimum boot configuration select bit.
When Min = 0, all fields must be independently configured. |
