3.1
The signals ‘P1.2/MISO’, ‘P1.4/SCK’ and ‘P1.3/MOSI’ signals are in some SW API’s used by the protocol
to store Routing Tables and HomeID in an external EEPROM. When these SW API’s are used, the
Application SW must not use these three signals. Table 9 shows the available SW API’s and in which the
SPI interface is used by the protocol.
3.2
Some SW API’s require an external EEPROM to be implemented on the Application PCB for protocol
information storage (like routing table, HomeID etc.). The SPI interface is used to access the EEPROM
and the ‘P1.5’ signal (EP5) is used by the Z-Wave Protocol as EEPROM Chip Select. To assure proper
control of the EEPROM chip select signal during reset and power-up a pull up resistor on the P1.5 should
be implemented as shown in Figure 8.
Only a part of the EEPROM is used for protocol data storage, the Application SW can use the remaining
memory area using an API call (see [3]). For the EEPROM memory area requirements of the protocol
API please refer to the documentation for the Z-Wave Controller code selected (see [3]).
