4.2 EIT events
4.2.1 Exception
(1) Reserved instruction exception (RIE)
The reserved instruction exception (RIE) occurs when execution of a reserved instruction (unimplemented
instruction) is detected.
(2) Address exception (AE)
The address exception (AE) occurs if an attempt is made to access an unaligned address with either
a load instruction or a store instruction.
4.2.2 Interrupt
(1) Reset interrupt (RI)
_______
The reset interrupt (RI) is always accepted when the RST signal is input. It has the highest priority.
(2) Wakeup interrupt (WI)
__________
The wakeup interrupt (WI) is accepted when the WKUP signal is input while the M32000D3FP is in
standby mode. It is only used to return from standby mode.
(3) System break interrupt (SBI)
______
The system break interrupt (SBI) is an interrupt request from the SBI pin. It is used when a break
in power source or an error from an external watchdog timer is detected. It is also used to return from
CPU sleep mode and to start an M32000D3FP set to slave mode.
(4) External interrupt (EI)
______
The external interrupt (EI) is an interrupt request from the INT pin. It is used by an interrupt from the
external peripheral I/O and can be masked by the IE bit in the PSW register. It is also used to return
from CPU sleep mode and to start an M32000D3FP set to slave mode.
4.2.3 Trap
The trap (TRAP) is a software interrupt which is generated by executing the TRAP instruction. A total
of 16 EIT vector entries are available for operands 0 to 15 of the TRAP instruction.
