UG-237
MPU_STIM_INTRQ_MB1 , IO, Address 0x4B[7]
INT1 interrupt mask for manual forced interrupt signal. When set the manual forced interrupt will trigger the INT1 interrupt and
MPU_STIM_INTRQ_ST will indicate the interrupt status.
Function
MPU_STIM_INTRQ_MB1
0 (default)
1
MPU_STIM_INTRQ_MB2 , IO, Address 0x4A[7]
INT2 interrupt mask for manual forced interrupt signal. When set the manual forced interrupt will trigger the INT2 interrupt and
MPU_STIM_INTRQ_ST will indicate the interrupt status.
Function
MPU_STIM_INTRQ_MB2
0 (default)
1
Multiple Interrupt Events
If an interrupt event occurs, and then a second interrupt event occurs before the system controller has cleared or masked the first
interrupt event, the ADV7619 does not generate a second interrupt signal. The system controller should check all unmasked interrupt
status bits as more than one may be active.
Table 70 lists the interrupt registers available and a brief description of their functions. For more details on the functionality of these
interrupt registers, refer to the ADV7619 Software Manual. Refer to the IO map section of the ADV7619 Software Manual for details of
the CP core interrupts and HDMI core interrupts.
