Bit | Field | Description |
---|---|---|
16 | Boot Devices | Boot Devices[16] used conjunction with Boot Devices[4] and Boot Devices [Used in conjunction with bits 3-1]
|
15-14 | Base Addr | Base address (0-3) used to calculate the branch address. Branch address is the chip select plus Base Address *16MB |
13 | Wait | Extended Wait

12 | Width | EMIF Width
|
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 CS0 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, CS0-CS3.

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 | Boot Devices | Boot Devices[4] used conjunction with Boot Devices[16] and Boot Devices [Use din conjunction with bits 3-1]
|
3-1 | Boot Devices | Boot Devices[3:1] used in conjunction with Boot Device [4]
