8.1.2.2 Device Configuration Field
The device configuration fieldsDEVSTAT[16:1] are used to configure the boot peripheral and, therefore, the bit
definitions depend on the boot mode.

Boot Devices Boot Device- used in conjunction with Boot Devices [Used in conjunction with bits 3-1]
0 = Sleep (default)
Others = Other boot modes
13
ARMen
Enable the ARM PLL
0 = PLL disabled
1 = PLL enabled
12
SYSEN
Enable the System PLL
0 = PLL disabled (default)
1 = PLL enabled
11-9 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 8-27 shows settings for various input clock frequencies.
8
Boot Master
Boot Master select
0 = ARM is boot master
1 = C66x is boot master
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 8-27 shows settings for various input clock frequencies.

Min
Minimum boot configuration select bit.
0 = Minimum boot pin select disabled
1 = Minimum boot pin select enabled.
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.
3-1 Boot Devices Boot Devices[3:1] used in conjunction with Boot Device [14]
