Device Operations
This section describes the read, program, erase, simultaneous read/write operations, and reset features of
the Flash devices.
Operations are initiated by writing specific commands or a sequence with specific address and data patterns
into the command register (see
Table 8.1
). The command register itself does not occupy any addressable
memory location; rather, it is composed of latches that store the commands, along with the address and data
information needed to execute the command. The contents of the register serve as input to the internal state
machine; the state machine outputs dictate the function of the device. Writing incorrect address and data
values or writing them in an improper sequence may place the device in an unknown state, in which case the
system must write the reset command in order to return the device to the reading array data mode.
8.1
Device Operation Table
The device must be set up appropriately for each operation.
Table 8.1
describes the required state of each
control pin for any particular operation.

Notes
1. WP# controls the two outermost sectors of the top boot block or the two outermost sectors of the bottom boot block.
2. DQ0 reflects the sector PPB (or sector group PPB) and DQ1 reflects the DYB.
