The MODE SELECT command sets various device operating modes.
The PF (Page Format) bit must be 1. If the PF bit is 0, the command responds
with Check Condition.
When the SP (Save Pages) bit is 1, the ODD saves all parameter values transferred
to the flash ROM.
Parameter List Length specifies the number of bytes in the mode parameters to be
transferred. If it is 0, the command does not carry out transfer and ends normally.
If the transferred mode parameters are insufficient, the command responds with
Check Conditions.
Table 4.46 lists mode parameters supported.
