9.1.2.2.2.2 I²C Master Mode
In master mode, the I²C device configuration uses ten bits of device configuration instead of seven as
used in other boot modes. In this mode, the device makes the initial read of the I²C EEPROM while the
PLL is in bypass mode. The initial read contains the desired clock multiplier, which must be set up prior to
any subsequent reads.

Description
Reserved
Parameter Table Index: 0-7
This value specifies the parameter table index when the C66x is the boot master
This value specifies the start read address at 8K times this value when the ARM is the boot master
I²C bus address slave device
• 0 = I²C slave boot bus address is 0x50 (default)
• 1 = I²C slave boot bus address is 0x51
• 2 = I²C slave boot bus address is 0x52
• 3 = I²C slave boot bus address is 0x53
Boot Master select
• 0 = ARM is boot master
• 1 = C66x is boot master
Reserved
I²C port number
• 0 = I²C0 (default)
• 1 = I²C1
• 2 = I²C2
• 3 = Reserved
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.
