Controller Status Register Check

Plane1 / Plane2 current : Invalid (Fixed to 0)

Plane1 / Plane2 previous: Invalid (Fixed to 0)

A1, A2, A3 : Address of DataRAM to be written

INT: Indicator for DataRAM’s Status (Ready=High, Busy=Low)

Controller Status Register Check Plane1 / Plane2 current : Invalid Plane1 / Plane2 previous: Pass=0, Fail=1

Controller Status Register Check Plane1 / Plane2 current : Pass=0, Fail=1 Plane1 / Plane2 previous: Pass=0, Fail=1

Ongoing Status : Indicated by OnGo bit in Controller Status Register [15] (F240h)

4KB data input : Asynch Write / Synch Write available.

Command input and INT pin behavior is based on ‘INT auto mode’.

In ‘INT manual mode’, writing ‘0’ to interrupt register is required before command issue.
