9.1.2.2.2 I²C Boot Device Configuration
9.1.2.2.2.1 I²C Passive Mode
In passive mode, the device does not drive the clock, but simply acks data received on the specified
address.

Table 9-5. I²C Passive Mode Device Configuration Field Descriptions
Description
I²C Slave boot bus address
• 0 = I²C slave boot bus address is 0x00
• 1 = I²C slave boot bus address is 0x10 (default)
• 2 = I²C slave boot bus address is 0x20
• 3 = I²C slave boot bus address is 0x30
Boot Device[14] used in conjunction with Boot Devices [Used in conjunction with bits 3-1]
• 0 = Other boot modes
• 1= I²C Slave boot mode
I²C port number
• 0 = I²C0
• 1 = I²C1
• 2 = I²C2
• 3 = Reserved
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 9-23 shows settings for various input clock frequencies.
Boot Master select
• 0 = ARM is boot master
• 1 = C66x is boot master
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 9-23 shows settings for various input clock frequencies.
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.
Boot Devices[3:1] used in conjunction with Boot Device [14]
• 000 = I²C Slave
• Others = Other boot modes
