Table 25: STS Configuration Register
Program OTP Register
In case of 256 Mb device (2x128), the command sequence must be repeated for each die at its base address
In case of 256 Mb device (2x128), keep the second cycle to the same address. (ie. Do not toggle A24 for the second cycle)
During Suspend, array-read operations are not allowed in blocks being erased or
A block-erase under program-suspend is not allowed. However, word-program under
erase-suspend is allowed, and can be suspended. This results in a simultaneous erase-
suspend/ program-suspend condition, indicated by SR[7,6,2] = 1.
To resume a suspended program or erase operation, issue the Resume command to
any device address. The read mode of the device is automatically changed to Read
Status Register. The operation continues where it left off, STS (in RY/BY# mode) goes
low, and the respective Status Register bits are cleared.
When the Resume command is issued during a simultaneous erase-suspend/ program-
suspend condition, the programming operation is resumed first. Upon completion of the
programming operation, the Status Register should be checked for any errors, and
cleared. The resume command must be issued again to complete the erase operation.
Upon completion of the erase operation, the Status Register should be checked for any
errors, and cleared.
Status Signal (STS)
The STATUS (STS) signal can be configured to different states using the STS
remains in that configuration until another Configuration command is issued or RP# is
asserted low. Initially, the STS signal defaults to RY/BY# operation where RY/BY# low
indicates that the WSM is busy. RY/BY# high indicates that the state machine is ready
for a new operation or suspended.
To reconfigure the STATUS (STS) signal to other modes, the Configuration command is
given followed by the desired configuration code. The three alternate configurations are
all pulse mode for use as a system interrupt as described in the following paragraphs.
For these configurations, bit 0 controls Erase Complete interrupt pulse, and bit 1
controls Program Complete interrupt pulse. Supplying the 0x00 configuration code with
the Configuration command resets the STS signal to the default RY/BY# level mode.
