Key-Input Interrupt
2.13 Key-Input Interrupt Usage
Figure 2.13.1. Memory map of key-input interrupt-related registers
2.13.1 Overview of the key-input interrupt usage
Key-input interrupt occurs when a falling edge is input to P10
of the key-input interrupt usage:
(1) Enabling/disabling the key-input interrupt
(2) Occurrence timing of the key-input interrupt
(3) How to determine a key-input interrupt
(4) Registers related to the key-input interrupt
The key-input interrupt can be enabled and disabled using the key-input interrupt register. The key-
input interrupt is affected by the interrupt priority level (IPL) and the interrupt enable flag (I flag).
With key-input interrupt acceptance enabled, pins P10
key-input interrupt pins (KI
key-input interrupt pin. At this moment, the level of other key-input interrupt pins must be “H”. No
interrupt occurs when the level of other key-input interrupt pins is “L”.
A key-input interrupt occurs when a falling edge is input to one of four pins, but each pin has the same
vector address.
Therefore, read the input level of pins P10
mine the interrupted pin.
Figure 2.13.1 shows the memory map of key-input interrupt-related registers, and Figure 2.13.2
shows key-input interrupt-related registers.
