Mode. These bits select the mode of operation, as follows:
00: Reset
01: Normal
10: Deep Power-Down
MDWREN (Mode Write Enable). The value 1 must be written to this bit when changing the
mode of operation. It always returns 0 when read.
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.
These two registers are identical and contain information about the DiskOnChip
G4 operational mode. 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 the DiskOnChip G4 memory space, except for
reads from the Programmable Boot Block space.
