This value can range from 0 to 0xf. See Table 10-13. |
11-9 | Reserved/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 reserved. |
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. Default system reference clock is 156.25 MHz. Table 10-27 shows settings for various input clock frequencies. |
