After programming has been carried out, the e5561 sends an Fh preburst followed by
terminator 1. After that, the data just programmed is read out of the EEPROM and sent
in loop with terminator 1. This enables the base station to detect a malprogramming by
comparing the data transmitted with the data read out after programming. This mode
remains until a POR occurs or another gap is detected.

Direct-access Mode
The direct-access mode is typically used to read out the content of a single block of the
EEPROM. The write sequence is shown in Figure 21. Following the OPcode 10, the
address of the block to be read has to be sent (LSB first).
Figure 21. Direct-access Mode Write Sequence
It is always possible to read the content of block 0 and the four blocks of the ID code.
The blocks containing the crypto-key (blocks 5 to 8) can only be accessed when the cor-
responding lock-bit in block 9 is not set. Therefore, there is no possibility for a non-
authorized person to read out or modify the crypto key if it is locked. Figure 23 shows
the direct-access-mode data stream. After the write sequence, an FFh preburst is sent
followed by terminator 1. After that, the addressed block and terminator 1 are sent in
loop.
