Section 4 Exception Processing
Exception Type
General interrupt requests
Note: Exception codes H'120, H'140, and H'3E0 are reserved.
4.1.5
If a general exception event occurs when the BL bit in SR is 1, the CPU's internal registers are set
to their post-reset state, other module registers retain their contents prior to the general exception,
and a branch is made to the same address (H'A0000000) as for a reset.
If a general interrupt occurs when BL
until the BL bit is cleared to 0 by software. For reentrant exception processing, the SPC and SSR
must be saved and the BL bit in SR cleared to 0.
4.1.6
The RTE instruction is used to return from exception processing. When RTE is executed, the SPC
value is set in the PC, and the SSR value in SR, and the return from exception processing is
performed by branching to the SPC address.
