10.7.4
DcScratch register (R/W: 0278h)
This 16-bit register can be used by the firmware to save and restore information. For
example, the peripheral status before it enters the suspend state. The content of this
register will not be altered by a bus reset. The bit allocation is given in
Table 142
.
10.7.5
Unlock Device register (W: 027Ch)
To protect the registers from getting corrupted when the ISP1761 goes into suspend, the
write operation is disabled if the PWRON bit 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 144
.
