16 | Lane | When Boot Master =0 (ARM is Boot Master), Pin[16] is used as Lane.
When Boot Master =1 (C66x is Boot Master), Pin[16] is reserved. |

11-9 | Lane Setup/ARM PLL Setting | When Boot Master =0 (ARM is Boot Master), pin[11:9] used as ARM PLL Setting with all lanes enabled. The PLL default settings are determined by the [11:9] bits. This will set the PLL to the maximum clock setting for the device. The default value is 156.26 MHz. Table 10-27 shows settings for various input clock frequencies.
When Boot Master =1 (C66x is Boot Master), pin [11:9] 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 = 1, a predetermined set of values is configured (see the Device Configuration Field Descriptions table for configuration bits with a "(default)" tag added in the description column). When Min = 0, all fields must be independently configured. |

In SRIO boot mode, both the message mode and DirectIO mode will be enabled by default. If use of the memory reserved for received messages is required and reception of messages cannot be prevented, the master can disable the message mode by writing to the boot table and generating a boot restart.
