High byte function code group number, A0～F31, U0, U1, respectively,
corresponding to the high byte address is 00H～1FH, 30H, 31H.
Low byte of the group function code number, from 0 to 99 corresponding
to the low byte address is 00H～63H.
For example: Modify b0.02 function code value, no power-down when
storing the corresponding register address (referred to as RAM address)
to 0102H.
EEPROM is frequently modified, will reduce the life of the EEPROM. If
you modify the value of the function code-down storage needs, you can
make this function code is the highest position a high address. Note that
this address is only to write, not read.
For example: Modify b0.02 function code value, and the corresponding
need to power down when storing the register address (referred to as
EEPROM address) to 8102H.
