15-13 | First Block | First Block. This value is used to calculate the first block read. The first block read is the first block value *16. |

11-9 | Chip Sel/ARM PLL Setting | When Boot Master = 0 (ARM is Boot Master), Pin[11:9] used as ARM PLL Setting and the chip select region CS2 is used. 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] used as Chip Sel that specifies the chip select region, CS2-CS5.

8 | Boot Master | Boot Master select
|
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. Table 10-27 shows settings for various input clock frequencies. |
4 | Min | Minimum boot pin select. When Min is 1, it means that the BOOTMODE [15:3] pins are don't cares. Only BOOTMODE [2:0] pins (DEVSTAT[3:1]) will determine boot. Default values are assigned to values that would normally be set by the other BOOTMODE pins when Min is 0.
