7. INTERRUPT FUNCTIONS AND TEST FUNCTIONS
The
μ
PD750108 has seven interrupt sources and two test sources. One test source, INT2, has two types of edge
detection testable input pins.
The interrupt control circuit of the
μ
PD750108 has the following functions.
(1) Interrupt functions
Hardware controlled vectored interrupt function which can control whether or not to accept an interrupt using
the interrupt flag (IE
×××
) and interrupt master enable flag (IME).
The interrupt start address can be set arbitrarily.
Multiple interrupt function which can specify the priority by the interrupt priority specification register (IPS)
Test function of an interrupt request flag (IRQ
×××
)
(The software can confirm that an interrupt occurred.)
Release of the standby mode (Interrupts released by an interrupt enable flag can be selected.)
(2) Test functions
Whether test request flags (IRQ
×××
) are issued can be checked with software.
Release of the standby mode (A test source to be released can be selected with test enable flags.)
