Chapter 15 Interrupt Controller

15. Interrupt Controller

15.1 Characteristics

The TX4937 on-chip Interrupt Controller (IRC) receives interrupt requests from the TX4937 on-chip

peripheral circuitry as well as external interrupt requests then generates interrupt requests to the TX49/H3

processor core.

Also, the Interrupt Controller has a 16-bit flag register that generates interrupt requests to either external

devices or to the TX49/H3 core.

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).
