8. QUERY COMMAND AND COMMON FLASH
INTERFACE (CFI) MODE
MX28F160C3T/B is capable of operating in the CFI mode.
This mode allows the host system to determine the
manufacturer of the device such as operating param-
eters and configuration. Two commands are required in
CFI mode. Query command of CFI mode is placed first,
then the Reset command exits CFI mode. These are
described in Table 3.
The single cycle Query command is valid only when the
device is in the Read mode, including Erase Suspend,
Program Suspend, Standby mode, and Read ID mode;
however, it is ignored otherwise.
The Reset command exits from the CFI mode to the
Read mode, or Erase Suspend mode, Program Suspend
or read ID mode. The command is valid only when the
device is in the CFI mode.
