Data EEPROM
Figure 24-18. FSK Modulation
The internal data EEPROM offers 2 pages of 512 bits each. Both pages are organized as 32 ×
16-bit words. The programming voltage as well as the write cycle timing is generated 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
• Data handling for read and write is performed using the serial interface MCL.
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.
