2013-02-27 Thread Kuo-Jung Su
From: Kuo-Jung Su The BIT6 of Status Register(SR): SR[6] behaves the same as R/B# pin SR[6] = 0 indicates the device is busy; SR[6] = 1 means the device is ready Some NAND flash controller (i.e. ftnandc021) relies on the SR[6] to determine if the NAND flash erase/program is success or e
