Keyboard Interrupts (S08KBIV2)
9.2
The KBI input pins can be used to detect either falling edges, or both falling edge and low level interrupt
requests. The KBI input pins can also be used to detect either rising edges, or both rising edge and high
level interrupt requests.
The signal properties of KBI are shown in
9.3
The KBI includes three registers:
Refer to the direct-page register summary in the
all KBI registers. This section refers to registers and control bits only by their names.
Some MCUs may have more than one KBI, so register names include placeholder characters to identify
which KBI is being referenced.
9.3.1
KBISC contains the status flag and control bits, which are used to configure the KBI.
