ATA555815M01-PP 数据手册

ATA5558 [Preliminary]

A valid Write command can be used for programming a data block of 33 bits – including the

associated lock bit – into an addressed location of either memory section. Once locked

(lock bit = 1), the entire block including the lock bit itself can no longer be reprogrammed

selectively.

The system memory section is situated at the upper end of the (6-bit) memory address range

and contains all system parameters and configuration settings. This area has restricted access

(see Figure 2-5 on page 7) and the majority of blocks can only be read or written after the suc-

cessful execution of the appropriate Password Login command (see Table 7-1 on page 24).

All the configuration settings are allocated in block 63 (see Figure 2-7 on page 9) and the pass-

word protection security information in block 62 (see Figure 2-6 on page 7).

2.6.2

Traceability Data

The traceability information is programmed and locked into the traceability blocks (59-61) by

Atmel during the production test.
