Reset:
• SOF: Start of Frame Interrupt Status Register
When set to one this flag indicates that a start of frame event has been detected. This flag is reset after a read operation.
• DIS: LCD Disable Interrupt Status Register
When set to one this flag indicates that the horizontal and vertical timing generator has been successfully disabled. This
flag is reset after a read operation.
• DISP: Power-up/Power-down Sequence Terminated Interrupt Status Register
When set to one this flag indicates whether the power-up sequence or power-down sequence has terminated. This flag is
reset after a read operation.
• FIFOERR: Output FIFO Error
When set to one this flag indicates that an underflow occurs in the output FIFO. This flag is reset after a read operation.
• BASE: Base Layer Raw Interrupt Status Register
When set to one this flag indicates that a Base layer interrupt is pending. This flag is reset as soon as the BASEISR register
is read.
• OVR1: Overlay 1 Raw Interrupt Status Register
When set to one this flag indicates that an Overlay 1 layer interrupt is pending. This flag is reset as soon as the OVR1ISR
register is read.
• HEO: High End Overlay Raw Interrupt Status Register
When set to one this flag indicates that a Hi End layer interrupt is pending. This flag is reset as soon as the HEOISR regis-
ter is read.
• HCR: Hardware Cursor Raw Interrupt Status Register
When set to one this flag indicates that a Hardware Cursor layer interrupt is pending. This flag is reset as soon as the
HCRISR register is read.
