7.25 Cursor Raw Interrupt Status register (CRSR_INTRAW, RW - 0xFFE1

0C28)

The CRSR_INTRAW register is set to indicate a cursor interrupt. When enabled via the
CrsrIM bit in the CRSR_INTMSK register, provides the interrupt to the system interrupt
controller.

The contents of the CRSR_INTRAW register are described in

Table 12–284

.

7.26 Cursor Masked Interrupt Status register (CRSR_INTSTAT, RW -

0xFFE1 0C2C)

The CRSR_INTSTAT register is set to indicate a cursor interrupt providing that the
interrupt is not masked in the

CRSR_INTMSK

register.

The contents of the CRSR_INTSTAT register are described in

Table 12–285

.

CrsrRIS

Cursor raw interrupt status.

The cursor interrupt status is set immediately after the last data
is read from the cursor image for the current frame.

This bit is cleared by writing to the CrsrIC bit in the
CRSR_INTCLR register.

CrsrMIS

Cursor masked interrupt status.

The cursor interrupt status is set immediately after the last data
read from the cursor image for the current frame, providing that
the corresponding bit in the CRSR_INTMSK register is set.

The bit remains clear if the CRSR_INTMSK register is clear.

This bit is cleared by writing to the CRSR_INTCLR register.
