• Manufacturer Part Number: upd70f3422gj-gae-qs-ax
• Description: 32-bit Single-chip Microcontroller
• Manufacturer: Renesas Electronics Corporation.

Interrupt Controller (INTC)
5.3.8 External maskable interrupts
5.3.9 Software interrupts
This microcontroller provides maskable external interrupts INTPn with the
following features:
• Analog input filter (refer to “Analog filtered inputs“ on page 102)
• Interrupt detection selectable for each interrupt input:
• Wakeup capability from stand-by mode of INTPn upon
For configuration of the external interrupt events refer to “Edge and Level
Detection Configuration“ on page 218.
This microcontroller provides maskable software interrupts to for processing of
an interrupt service routine by the application software.
For initiating a software interrupt the interrupt request flag xxIC.xxIF of the
concerned software interrupt “xx” must be set to 1. The following processing is
identical to that of all other maskable interrupts.
