Mode. These bits select the mode of operation, as follows:
00: Reset
01: Normal
10: Deep Power-Down
MDWREN (Mode Write Enable). This bit must be set to 1 before changing the mode of operation.
BDET (Boot Detect). This bit is set whenever the device has entered Reset mode as a result of the
Boot Detector triggering. It is cleared by writing a 1 to this bit.
RST_LAT (Reset Latch). This bit is set whenever the device has entered the Reset mode as a
result of the RSTIN# input signal being asserted or the internal voltage detector triggering. It is
cleared by writing a 1 to this bit.
Reserved for future use.
RFU_0
These two registers are identical and contain information on the operation mode of DiskOnChip.
After writing the required value to the DiskOnChip Control register, the complement of that data
byte must also be written to the Control Confirmation register. The two writes cycles must not be
separated by any other read or write cycles to DiskOnChip Millennium Plus memory space,
except for reads from the Programmable Boot Block space.
