See
Chapter 14.0, “Write State Machine Current/Next States,”
Issuing this command suspends the currently executing Program/Erase operation.
To indicate when the operation has been successfully suspended, the Status Register sets
either the program suspend (SR.2) or erase suspend (SR.6), and sets the WSM status bit
(SR.7) to 1 (ready).
The WSM continues to idle in the SUSPEND state, regardless of the state of all input-control
pins except RP#, which immediately shuts down the WSM and the remainder of the device, if it
is driven to V
See
“Suspending and Resuming Programming” on page
This command places the flash memory device into Read-Status Register mode. Reading the
device outputs the contents of the Status Register, regardless of the address presented to the
device.
The flash memory device automatically enters this mode after a Program or Erase operation is
initiated. See
The WSM can set the block-lock status (SR.1), V
erase status (SR.5) bits in the Status Register to 1. However, the WSM cannot clear these bits
to 0. Issuing this command clears these bits to 0.
Places the flash memory device into the intelligent-identifier-read mode, so that reading the
device outputs the manufacturer and device codes (A
device; all other address inputs must be 0). See
