Summary of Command Sequence Sample Clauses
Summary of Command Sequence as a function of device and mode
1. The system must drive the lowest order addresses to access all the device’s array data when the device is configured in x8 mode. Therefore, word or double addressing where the lower addresses are not toggled by the system is “Not Applicable” for x8-Configured devices.
2. Flash devices may or may not have address sensitive query commands. Device drivers should always supply 55h on the address bus (55h, AAh, and 154h respectively for command address location in bytes on x8, x16 and x32 data bus configured devices) and 98h on the data bus to enter query mode, however Flash devices may choose to ignore the address bus and enter query mode if 98h is seen on the data bus only.
3. Same as note 1 above but change x8 references to x16.
