8.1. Characteristics
The TX4939 on-chip Interrupt Controller (IRC) receives interrupt requests from the TX4939 on-chip peripheral circuitry as
well as external interrupt requests and in turn generates interrupt requests to the TX49/H4 processor core.
Also, this Interrupt Controller has a 16-bit flag register that generates interrupt requests either to the external devices or to
the TX49/H4 core.
The Interrupt Controller has the following characteristics.
Rev. 3.1 November 1, 2005
Supports interrupts from 47 types of on-chip peripheral circuits and a maximum of 3 external interrupt signal
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
The Interrupt Controller contains a 16-bit readable/write-able flag register which can be programmed to issue
inputs.
