software interrupts, but these interrupts are directly reported to the TX49/H3 core independently of this
Interrupt Controller. Please refer to the “64-bit TX System RISC TX49/H2, TX49/H3, TX49/H4 Core

Interrupt request detection
IDE bit of the Interrupt Detection Enable Register (IRDEN) is set to “1.” All interrupts detected by the
Interrupt Controller are masked when this bit is cleared.

for each interrupt source indicated in Table 15.3.1.
In addition to the above, the TX49/H3 core has a TX49/H3 core internal timer interrupt and two
In order to perform interrupt detection, each register of the Interrupt Controller is initialized, then the
It is possible to set each interrupt factor detection mode using Interrupt Detection Mode Register 0
The detected interrupt factors can be read out from the Interrupt Pending Register (IRPND).
Interrupt levels from 0 to 7 are assigned to each detected interrupt using the Interrupt Level Register
The priorities set by these interrupt levels will be given higher priority than the priorities provided
