2.8.22 Interrupt Status Register F241h (R/W)
This Read/Write register shows status of the MuxOneNAND interrupts.
In DDP, INT register will not be written if DFS is not set.
F241h, defaults = 8080h after Cold Reset; 8010h after Warm/Hot Reset
Interrupt (INT)
This is the master interrupt bit. The INT bit is wired directly to the INT pin on the chip. Upon writing '0' to the INT bit, the INT pin goes low if
INTpol is high and goes high if INTpol is low.
INT Interrupt [15]
Read Interrupt (RI)
This is the Read interrupt bit.
