WRITE cycle. The RDY/BSY pin will output the BUSY
status (LOW) one t
clock (the last data bit) and will stay LOW until the write
cycle is complete. Then it will output a logical “1” until the
next WRITE cycle. The RDY/BSY output is not affected
by the input of CS.
An alternative to get RDY/BSY status is from the DO pin.
During a write cycle, asserting a LOW input to the CS pin
will cause the DO pin to output the RDY/BSY status.
Bringing CS HIGH will bring the DO pin back to a high
impedance state again. After the device has completed
a WRITE cycle, the DO pin will output a logical “1” when

the device is deselected. The rising edge of the first “1”
input on the DI pin will reset DO back to the high
impedance state again.
The WRITE operation can be halted anywhere in the
operation by the RESET input. If a RESET pulse occurs
during a WRITE operation, the device will abort the
operation and output a READY status.
NOTE: Data may be corrupted if a RESET occurs while
the device is BUSY. If the reset occurs before the BUSY
period, no writing will be initiated. However, if RESET
occurs after the BUSY period, new data will have been
written over the old data.
