MX23L1010 Datasheet
MX23L1010 Price
MX23L1010 on stock The AMD-K5 processor implements write allocate by providing a global write allocate enable bit, three range-protection enable bits, and two memory range registers. The global write allocate enable bit is accessed using the Hardware Configuration Register (HWCR). The memory range registers and range enable bits are programmed by read/write MSR instructions. Login Command Sending login command is necessary before sending any password protected command. In Login command a 32 bit password including parity bits is sent as command parameter. The 32 bit password is sent according to Data structure defined above (45 bits including parity). In the case the parity bits are correct and 32 bit password sent matches with content of word 2 a login flag is set. Login flag is set until next power-up, which means that Login command has to be sent only once after power up to enable execution of password protected commands. In case Login command is successfully processed lC responds with preamble pattern (00001010) and returns in Default Read mode. In case the Login is not accepted (wrong password or error in parity) a pattern 00000001 is sent and lC returns in Default Read mode. |
