System area
This area is used to modify the settings of the SRIX4K. It contains 3 registers:
OTP_Lock_Reg, Fixed Chip_ID and ST Reserved. See
A Write_block command in this area will not erase the previous contents. Selected bits can
thus be set from 1 to 0. All bits previously at 0 remain unchanged. Once all the 32 bits of a
block are at 0, the block is empty and cannot be updated any more.
