information

Accessible by IDT only

According to Table 3.3.

According to Table 3.2 with information bits corresponding to the left column; DEXG if I4 = ‘0’, WPAR if I4 = ‘1’. Note: In contrast to

regular WPAR/DEXG calls, the slave always returns the received data bits I3 to I0 for these master calls.

4.4.

Safety Area Programming (SAP5S only)

The Safety Area contains the cryptographic code table, which consists of 8 data words and one swap-flag each

(refer to section 5.18 for an explanation of the SAP5 Safety Mode). Similar to the Firmware Area, it can be

protected against undesired data modification by setting the Safety_Program_Mode_Disable flag; see address 31

in Table 4.4.

NOTE: Once the Safety_Program_Mode_Disable flag is set, the Safety Area of the EEPROM is permanently

locked; i.e., write access to the Safety Area as described in Table 4.4 is possible only as long as the

Safety_Program_Mode_Disable flag is not set.
