16.5.1.3 Timing Diagram
The following diagram shows programming of 5 bytes into the E²PROM:
Explanation: It is assumed, that the SL RC400 finds and reads Byte 0 before the µ-Processor is able to write
Byte 1 (t
t
E²PROM starting byte-address is e.g. 4C
following data bytes into the E²PROM input buffer. Copying Byte 3, it detects, that this data byte has to be
programmed at the E²PROM byte-address 4F
automatically starts a programming cycle. In the next turn, Byte 4 will be programmed at the E²PROM byte-
address 50
E²PROM programming activity will be set.
Although all data has been programmed into the E2PROM, the SL RC400 stays in the WriteE2-Command.
Writing further data to the FIFO would lead to further E²PROM programming, continuing at the E²PROM
byte-address 51
16.5.1.4 Error Flags for the WriteE2 Command
Programming is inhibited for the E²PROM blocks 0 (E²PROM’s byte-address 00
these addresses sets the flag AccessErr. No programming cycle is started (for the E²PROM memory
organisation refer to chapter 6.). It is strictly recommended to use only the described E²PROM address area.
