4.1 Read Array Command
Upon initial device power-up and after exit from reset
mode, the device defaults to read array mode. This op-
eration is also initiated by writing the Read Array com-
mand. The device remains enabled for reads until an-
other command is written. Once the internal WSM has
started a sector erase, word write or sector lock con-
figuration the device will not recognize the Read Array
command until the WSM completes its operation unless
the WSM is suspended via a Sector Erase Suspend or
Word Write Suspend command. If RP=VIL device is in
read Read Array command mode, this read operation no
longer requires VPP. The Read Array command func-
tions independently of the VPP voltage and RP can be
VIH.
4.2 Read Configuration Codes Command
The configuration code operation is initiated by writing
the Read Configuration Codes command (90H). To re-
turn to read array mode, write the Read Array Command
(FFH). Following the command write, read cycles from
addresses shown in Table 4 retrieve the manufacturer,
device, sector lock configuration codes and the protec-
tion register(see Table 4 for configuration code values).
To terminate the operation, write another valid command.
Like the Read Array command, the Read Configuration
Codes command functions independently of the VPP
voltage and RP can be VIH. Following the Read Configu-
ration Codes command, the information is shown:

4.3 Read Status Register Command
CUI writes read status command (70H). The status reg-
ister may be read to determine when a sector erase,
word write or lock-bit configuration is complete and
whether the operation completed successfully. (refer to
table 6) It may be read at any time by writing the Read
Status Register command. After writing this command,
all subsequent read operations output data from the sta-
tus register until another valid command is written. The
status register contents are latched on the falling edge
of CE or OE, whichever occurs last. CE or OE must
toggle to VIH before further reads to update the status
register latch. The Read Status Register command func-
tions independently of the VPP voltage. RP can be VIH.
4.4 Clear Status Register Command
Status register bits SR.5, SR.4, SR.3 or SR.1 are set to
"1"s by the WSM and can only be reset by the Clear
Status Register command (50H). These bits indicate
various failure conditions (see Table 6). By allowing sys-
tem software to reset these bits, several operations (such
as cumulatively erasing multiple sectors or writing sev-
eral words in sequence) may be performed. The status
register may be polled to determine if an error occurred
during the sequence.
To clear the status register, the Clear Status Register
command (50H) is written on CUI. It functions indepen-
dently of the applied VPP Voltage. RP can be VIH. This
command is not functional during sector erase or word
write suspend modes.
