Bits Name Default Description
[31:1] - - Reserved.
[0] IRQ_SET -

This bit sets the interrupt:

0 = The MPC ignores the write, so the interrupt state remains unchanged.

1 = The MPC sets the interrupt by:

  • Setting IRQ_STAT.IRQ_STAT = 1.
  • Setting the irq signal HIGH, if IRQ_EN.IRQ_EN == 1.


    When the MPC sets the interrupt, it does not alter the value of the IRQ_INFO1 and IRQ_INFO2 registers.
