5.2.2.6
Keyboard interrupt functions are available on PC0-PC5. Each port pin can be individually
configured for the keyboard interrupt function in the KBI register at $0010. Once configured, an
interrupt is recognized by a high to low transition (negative edge) sensed on the pin and the I-bit
in the CCR is also cleared.
The interrupt service routine is specified by the contents of the memory locations $3FF0 and
$3FF1.
