Any WPAR or DEXG call initializes an autonomous write process within the IC. The status of the write process

can be monitored by evaluating the status register of the IC the same way described above. Since the IC is

still in Safety Program Mode, the address within the Read_Status master call doesn’t care. In order to execute

as many write procedures as desired, the Safety Program Mode must not be left. However, the SAP5 will

leave the Safety Program Mode and start it’s initialization procedure if it receives a Reset_Slave (RES) master

call to any desired slave address.

Any attempt to access one of the not available E²PROM address locations (0, 9 … 30) through a

Write_Parameter (WPAR) or Data_Exchange (DEXG) command will be ignored.

There is no direct read access to the Safety Area data in Safety Program Mode.

An E²PROM verification procedure should be carried out e.g. by performing one complete AS-i safety cycle

(8 DEXG calls in minimum 250

s intervals) in Safety Mode operation.
