(HW_BCH_STATUS0)
Reserved, always set these bits to zero.
1 = interrupt on debug stall mode is enabled. The irq is raised on every block
Reserved, always set these bits to zero.
1 = interrupt on completion of correction is enabled.
Reserved, always set these bits to zero.
AHB Bus interface Error Interrupt Status. Write a one to the SCT clear address to clear the interrupt
status bit.
DEBUG STALL Interrupt Status. Write a one to the SCT clear address to clear the interrupt status bit.
Reserved, always set these bits to zero.
This bit indicates the state of the external interrupt line. Write a one to the SCT clear address to clear
the interrupt status bit. NOTE: subsequent ECC completions will be held off as long as this bit is set. Be
sure to read the data from HW_BCH_STATUS0,1 before clearing this interrupt bit.
