Occurrence timing of the key-input interrupt
Determining a key-input interrupt
Related registers
With the Key-input interrupt enabled, Port 10 pins that are enabled in the Key-input mode register are set to input mode
and become Key-input interrupt pins (KI
a 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 any other key-input interrupt pins is "L".
A key-input interrupt occurs when the selected edge is input to one of 8 pins, (if they are all enabled in the Key-input
mode register) but each pin has the same vector address. Therefore, read the input level of Port P10 in the key-input
interrupt routine to determine the interrupted pin.
Figure 1.39 shows the memory map of key-input interrupt-related registers.
