In 8-bit mode, one, two, three or four bytes can can be accessed to send the same number of bus cycles.
Read-only view of NAND Ready_Busy Input pins.
State of the RDY/BUSY Timeout Flags. When any bit is set to '1' in this field, it indicates that a time out
has occurred while waiting for the ready state of the requested NAND device. Multiple bits may be set
simultaneously.
