Addresses 0080
are dedicated to firmware banks. Each area can hold one bank.
A firmware bank is a data block that contains:
•
•
•
The maximum size of a firmware bank is 5E00

Two parameters zones (7800
registers, STP parameters and profiles for Firmware Banks 1 and 2, respectively.
Note: Addresses in the parameters zone for Firmware Bank 2 are offset from the
The parameters zones are divided as follows (adresses for Firmware Bank 1 parameters
shown first, followed by addresses for Firmware Bank 2 parameters):
