Data EEPROM
4551C–4BMCU–01/04
Figure 90. FSK Modulation
The internal data EEPROM offers 2 pages of 512 bits each. Both pages are organized
as 32
erated on chip. To be compatible with the ROM parts, two restrictions have to be taken
into account:
•
•
The page select is performed by either writing “01h” (page 1) or “09h” (page 0) to the
EEPROM.

To use the same EEPROM page as with the ROM parts the application software has
to write the MCL-command “09h” to the EEPROM. This command has no effect for
the microcontroller if it is left inside the HEX-file for the ROM version.
Data handling for read and write is performed using the serial interface MCL.
