Product identifier:
Compatibility determination between the
front-end and the upgrade code
•
Compatibility code (0 x E0) – Describes the product’s
hardware revision
•
Model (0 x 9A)
•
Series (0 x 9B)
•
Firmware rev (0 x DD)
Compatibility Code:
A unique ASCII character set of up to 16
characters defining the hardware configuration.
Level_x: Device to be re-programmed:
The three µC’s are
interconnected within the module. The System Controller
always talks through the I2C interface. The I2C interface
transfers information to both the DC-DC and PFC µC’s
through the DC-DC µC. The level structure identifies where the
final destination resides.
