(1) Interrupt function
(2) Test function
PD753017 has eight types of interrupt sources and two types of test sources. Among the test sources, INT2
PD753017 has the following functions in the interrupt controller.
• Vectored interrupt function for hardware control, enabling/disabling the interrupt acceptance by the
• Can set any interrupt start address.
• Multiple interrupts wherein the order of priority can be specified by the interrupt priority select register
• Test function of interrupt request flag (IRQXXX). An interrupt generated can be checked by software.
• Release the standby mode. A release interrupt can be selected by the interrupt enable flag.
• Test request flag (IRQXXX) generation can be checked by software.
• Release the standby mode. The test source to be released can be selected by the test enable flag.
interrupt enable flag (IEXXX) and interrupt master enable flag (IME).
