SE97B
DDR memory module temp sensor with integrated SPD
7.10.1.3 Acknowledge polling
Acknowledge polling can be used to determine if the SE97B is busy writing or is ready to
accept commands. Polling is implemented by sending a Selective Read command
(described in Section 7.10.3
Read operations
) to the device. The SE97B will not
acknowledge the slave address as long as internal write is in progress.
7.10.2 Memory Protection
The lower half (the first 128 bytes) of the memory can be write protected by special
EEPROM commands without an external control pin. The SE97B features three types of
memory write protection instructions, and three respective read Protection instructions.
The level of write-protection (set or clear) that has been defined using these instructions
remained defined even after power cycle.
The memory protection commands are:
" Permanent Write Protection (PWP)
" Reversible Write Protection (RWP)
" Clear Write Protection (CWP)
" Read Permanent Write Protection (RPWP)
" Read Reversible Write Protection (RRWP)
" Read Clear Write Protection (RCWP)
Table 6
is the summary for normal and memory protection instructions.
[1] The most significant bit, bit 7, is sent first.
[2] V
I(ov)
ranges from 7.0 V to 10 V.
[3] A0, A1, and A2 are compared against the respective external pins on the SE97B. Do not apply V
I(ov)
to the A0 pin during
Normal EEPROM read/write, Permanent Write Protection (PWP) and Read PWP.
This special EEPROM command consists of a unique 4-bit fixed address (0110b) and the
voltage level applied on the 3-bit hardware address. Normally, to address the memory
array, the 4-bit fixed address is 1010b. To access the memory protection settings, the
4-bit fixed address is 0110b. Figure 13
and Figure 14
show the write and read protection
sequence, respectively.
