15.3 Detailed Explanation

15.3.1

Interrupt Sources

The TX4925 has as interrupt sources interrupts from 21 types of on-chip peripheral circuits and 8
external interrupt signals.
Table 15.3.1 lists the interrupt sources. Signals with the lower interrupt number have the higher
priority. Refer to section "15.3.4 Interrupt Priority Assigning" for the priorities.
Priority
In addition to the above, the TX49/H2 core has a TX49/H2 core internal timer interrupt and two
software interrupts, but these interrupts are directly reported to the TX49/H2 core independently of this
Interrupt Controller. Please refer to the "64-Bit TX System RISC TX49/H2 Core Architecture" for more
information.
