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 4.47 lists mode parameters supported.
