This section describes the operational features of flash memory. Operations are
command-based, wherein command codes are first issued to the device, then the
device performs the desired operation. All command codes are issued to the device
using bus-write cycles. A complete list of available command codes can be found in
Section 10.0, “Device Command Codes” on page
The Status Register (SR) is an 8-bit, read-only register that indicates device status and
operation errors. To read the Status Register, issue the Read Status Register command.
Subsequent reads output Status Register information on DQ[7:0], and 00h on
SR status bits are set and cleared by the device. SR error bits are set by the device, but
must be cleared using the Clear Status Register command. Upon power-up or exit from
reset, the Status Register defaults to 80h. Page-mode reads are not supported in this
read mode. Status Register contents are latched on the falling edge of OE# or the first
edge of CEx that enables the device. OE# must toggle to V
disabled before further reads to update the Status Register latch. The Read Status
Register command functions independently of V
