READY/BUSY
The device has a R/B output that provides a hardware method of indicating the completion of a frame program, erase or read seek
completion. The R/B pin is normally high but transitions to low after program or erase command is written to the command register or
a random read is begin after address loading. It returns to high when the internal controller has finished the operation. The pin is an
open-drain driver thereby allowing two or more R/B outputs to be Or-tied. Because pull-up resistor value is related to tr(R/B) and cur-
rent drain during busy(ibusy) , an appropriate value can be obtained with the following reference chart(Fig 10). Its value can be
determined by the following guidance.
