IDE and Flash Media Interface
13.5.3.1
13.5.4
There are 12 interrupt sources associated with the Flash Media interface. REGISTER
FLASHMEDIAINTSTAT allows the viewing of pending interrupts. Register FLASHMEDIAINTEN
allows the enabling of interrupts (‘1’ = enabled, ‘0’ = disabled). Some interrupts can be cleared by writing
a ‘1’ to the corresponding bit of the FLASHMEDIAINTCLEAR register.
