Read-Array Command

Upon initial device power-up and after exit from reset, the device defaults to the read array mode. This

operation can also be initiated by writing the Read-Array command. (See Table 8.) The device remains

available for array reads until another command is written. Once an internal Program/Erase operation

starts, the device will not recognize the Read-Array command until the operation is completed, unless

the operation is suspended via a Program/Erase Suspend command.

Read-Software-ID Command

The Read-Software-ID operation is initiated by writing the Read-Software-ID command. Following the

command, the device will output the manufacturer’s ID and device ID from the addresses shown in

Table 9. Any other valid command will terminate the Read-Software-ID operation.

The Read-Software-ID command is the same as the Read-Security-ID command. See “Security ID

Commands” on page 19.

Read-Status-Register Command

The Status register may be read to determine when a Sector-/Block-Erase or Program completes, and

whether the operation completed successfully. The Status register may be read at any time by writing

the Read-Status-Register command. After writing this command, all subsequent Read operations will

return data from the Status register until another valid command is written.

The default value of the Status register after device power-up or reset is 80H.

Address

1. Address shown in this column is for boot device only. Address locations should appear elsewhere in the 4 GByte sys-

tem memory map depending on ID strapping values on ID[3:0] pins when multiple LPC memory devices are used in a

system.
