[Shut-down signal output (SD select)]
*: Data (3 to 0)
[Shut-down mask]
*: Data (4): Unused.
Data (3)
These 4 bits are used to select what shut-down signal to generate. Alternatively, they are used to indicate
vendor or version code.
The shut-down select signals are released when the SLEEP signal changes form low to high.
These 3 bits are used to disable the shut-down function concerned. (One bit corresponds to one function.
When a bit is high, the corresponding function is disabled. Their default value is “LLLL”.)
