INTERRUPT FUNCTIONS
4.1
OUTLINE
The
μ
PD78366A is provided with powerful interrupt functions that can process interrupt requests from the
internal hardware peripherals and external sources. In addition, the following three interrupt processing modes
are available. In addition, four levels of interrupt priority can be specified.
Vectored interrupt processing
Macro service
Context switching
