Data Inputs/Outputs
Chip Enable, Device selected at VIL
Output Enable, Output at VIL and HIGH-Z at VIH
Write Enable, Write Mode at VIL and Read Mode at VIH
Hardware Write Protect, Highest & Lowest Sector Protect at VIL
Hardware Reset, device logic to standby and ready to read.
Ready/Busy Status, Indicates whether an Embedded Algorithm
is in progress or complete. At VIL, the device is actively engaged
in an Embedded Algorithm such as erasing or programming. At
HIGH-Z, the device is ready for read or a new command write -
requires external pull-up resistor to detect the HIGH-Z state.
Multiple devices may have their RY/#BY outputs tied together to
detect when all devices are ready.
