3.3 Reset Mode Operation
The Flex-MuxOneNAND has 4 reset modes: Cold/Warm/Hot Reset, and NAND Flash Array Reset. Section 3.3 discusses the operation of
these reset modes.
The Register Reset Table shows the which registers are affected by the various types of Reset operations.
Internal Register Reset Table
NOTE :
1a) RDYpol, RDYconf, INTpol, IOBE are reset by Cold reset. The other bits are reset by cold/warm/hot reset
1b) The other bits except OTPL and OTPBL are reset by cold/warm/hot reset.
2) ECC Status Register 1~4 are reset when any command is issued.
3) Refer to Device ID Register F001h.
4) Resetting during IDLE state, this is valid. But resetting during BUSY state, refer to Chapter 2.8.21.
5) To read NAND Flash Write Protection status, Block Address register must be written before.
