-Parameters
+Discussion
----------
-**interrupt**: the number of the interrupt (*int*)
-
-
-
-**function**: the function to call when the interrupt occurs; this
-function must take no parameters and return nothing. This function
-is sometimes referred to as an *interrupt service routine.*
-
-
-
-**mode** defines when the interrupt should be triggered. Four
-contstants are predefined as valid values:
-
-
-- **LOW** to trigger the interrupt whenever the pin is low,
-- **CHANGE** to trigger the interrupt whenever the pin changes
- value
-- **RISING** to trigger when the pin goes from low to high,
-- **FALLING** for when the pin goes from high to low.

+
+External Interrupts
+===================
+
+External interrupts can be used to trigger routines to run in response
+to changes in voltage on a pin. Each GPIO pin on the Maple can be used
+to detect transitions such as when the voltage goes from low to high,
+or from high to low. This technique can be used to avoid unnecessary
+polling of the state of a pin.
+

+
+
+Overview
+--------
+
+External interrupts are often used to detect when events happen
+outside of the microcontroller. These can be used to tell the Maple
+when events happen, such as when a sensor has data ready to be read,
+or when a button has been pushed. When such an event happens, an
+interrupt is raised and the Maple can react to it with a preset
+*interrupt handler*.
+
+Every GPIO pin on the Maple can be used as an external interrupt,
+subject to certain constraints; there can be a maximum of 16 different
+external interrupts set up at a time on the Maple. This is because the
+external interrupt lines on the STM32 are multiplexed between GPIO
+ports. In effect, this means that every pin on the Maple maps to a
+certain EXTI line, and within that EXTI line, only one of the pins
+that maps to it can be used as an external interrupt at a time.
+
+The following table shows which pins can be used on which lines.
+
+.. list-table::
+ :widths: 1 1
+ :header-rows: 1
+
+ * - EXTI Line
+ - Maple pins
+ * - EXTI0
+ - 2, 15, 27
+ * - EXTI1
+ - 3, 16, 28
+ * - EXTI2
+ - 1, 17, 25

+ * - EXTI4
+ - 10, 19
+ * - EXTI5
+ - 4, 13, 20
+ * - EXTI6
+ - 5, 12, 35
+ * - EXTI7
+ - 9, 11, 36
+ * - EXTI8
+ - 6, 14, 37
+ * - EXTI9
+ - 7, 25, 28

+
+.. note::
+

+ ``INPUT_PULLUP``, ``INPUT_PULLDOWN``).
