OTP_Lock_Reg
The 8 bits, b
bits in the SRIX4K. They control the write access to the 9 EEPROM blocks with addresses 7
to 15 as follows:
The OTP_Lock_Reg bits cannot be erased. Once write-protected, EEPROM blocks behave
like ROM blocks and cannot be unprotected.
Fixed Chip_ID (Option)
The SRIX4K is provided with an anticollision feature based on a random 8-bit Chip_ID. Prior
to selecting an SRIX4K, an anticollision sequence has to be run to search for the Chip_ID of
the SRIX4K. This is a very flexible feature, however the searching loop requires time to run.
For some applications, much time could be saved by knowing the value of the SRIX4K
Chip_ID beforehand, so that the SRIX4K can be identified and selected directly without
having to run an anticollision sequence. This is why the SRIX4K was designed with an
optional mask setting used to program a fixed 8-bit Chip_ID to bits b
area. When the fixed Chip_ID option is used, the random Chip_ID function is disabled.
