6.2.2 RAM MEMORY ACCESS
Only Basic Function Parameters, that is group parameters F0 to FE, and A0 to AF, can be accessed through their
RAM communication address.
The communication address to access to the RAM memory of the parameter, is represented in hexadecimal
format.
The RAM memory address is based in the EEPROM memory address, but changing the most significant digit for
another value. See the correspondence below:
