Unlock Device register (address: 7Ch)
To protect the registers from getting corrupted when the ISP1583 goes into suspend,
the write operation is disabled if bit PWRON in the Mode register is set to logic 0. In
this case, when the chip resumes, the Unlock Device command must be first issued
to this register before attempting to write to the rest of the registers. This is done by
writing unlock code (AA37h) to this register. The bit allocation of the Unlock Device
register is given in
Table 89
.
When bit PWRON in the Mode register is logic 1, the chip is powered. In such a case,
you do not need to issue the Unlock command because the microprocessor is
powered and therefore, the RD_N, WR_N and CS_N signals maintain their states.
