devices or to the TX49/H3 core.
The TX4937 on-chip Interrupt Controller (IRC) receives interrupt requests from the TX4937 on-chip
Also, the Interrupt Controller has a 16-bit flag register that generates interrupt requests to either external
The Interrupt Controller has the following characteristics.
•
•
•
•
Supports interrupts from 18 types of on-chip peripheral circuits and a maximum of 6 external
interrupt signal inputs
Sets 8 priority interrupt levels for each interrupt input
Can select either edge detection or level detection for each external interrupt when in the interrupt
detection mode
As a flag register used for interrupt requests, the Interrupt Controller contains a 16-bit
readable/writeable register and can issue interrupt requests to external devices as well as to the
TX49/H3 core (IRC interrupt).
