User manual
3.1.1 Register description
3.1.2 External Interrupt flag register (EXTINT - 0xE01F C140)
3.1 External interrupt inputs
Table 23.
[1]
The LPC2400 includes four External Interrupt Inputs as selectable pin functions. In
addition, external interrupts have the ability to wake up the CPU from Power-down mode.
This is controlled by the register INTWAKE, which is described in the Clocking and Power
Control chapter under the Power Control heading
The external interrupt function has four registers associated with it. The EXTINT register
contains the interrupt flags. The EXTMODE and EXTPOLAR registers specify the level
and edge sensitivity parameters.
Table 24.
[1]
When a pin is selected for its external interrupt function, the level or edge on that pin
(selected by its bits in the EXTPOLAR and EXTMODE registers) will set its interrupt flag in
this register. This asserts the corresponding interrupt request to the VIC, which will cause
an interrupt if interrupts from the pin are enabled.
Writing ones to bits EINT0 through EINT3 in EXTINT register clears the corresponding
bits. In level-sensitive mode the interrupt is cleared only when the pin is in its inactive
state.

Summary of system control registers
External Interrupt registers
Description
The External Interrupt Flag Register contains
interrupt flags for EINT0, EINT1, EINT2 and
EINT3. See
The External Interrupt Mode Register controls
whether each pin is edge- or level-sensitive.
See
The External Interrupt Polarity Register controls
which level or edge on each pin will cause an
interrupt. See
