The command register itself does not occupy any addressable memory loca- tion. The register is a latch used to store the com- mands, along with the address and data information needed to execute the command. The contents of the register serve as inputs to the internal state machine. The state machine outputs dictate the function of the device. Table 1 lists the device bus operations, the in- puts and control levels they require, and the resulting output. The following subsections describe each of these operations in further detail. Table 1. Device Bus Operations Legend: L = Logic Low = V IL, H = Logic High = VIH, VID = 11.5–12.5 V, VHH = 11.5–12.5V, X = Don’t Care, SA = Sector Address, AIN = Address In, DIN = Data In, DOUT = Data Out Notes: 1. Addresses are A21:A0 in doubleword mode; A21:A-1 in word mode. Sector addresses are A21:A15 in both modes. 2. The sector protect and sector unprotect functions may also be implemented via programming equipment. See the “Sector Group Protection and Unprotection” section. 3. If WP# = V IL, the first or last sector remains protected. If WP# = VIH, the first or last sector will be protected or unprotected as determined by the method described in “Sector Group Protection and Unprotection”. All sectors are unprotected when shipped from the factory (The SecSi Sector may be factory protected depending on version ordered.) 4. DIN or DOUT as required by command sequence, data polling, or sector protect algorithm (see Figure 2). Word/Byte Configuration The WORD# pin controls whether the device data I/O pins operate in the word or doubleword configuration. If the WORD# pin is set at V IH, the device is in double- word configuration, DQ31–DQ0 are active and con- trolled by CE# and OE#. If the WORD# pin is set at V IL, the device is in word configuration, and only data I/O pins DQ15–DQ0 are active and controlled by CE# and OE#. The data I/O pins DQ31–DQ16 are tri-stated, and the DQ23 and DQ31 pins are used as inputs for the LSB (A-1) ad- dress function. VersatileIO TM (V IO) Control The VersatileIO TM (V IO) control allows the host system to set the voltage levels that the device generates and tolerates on CE# and DQ I/Os to the same voltage level that is asserted on V IO. See Ordering Information for V IO options on this device.
