5.6
When an address error or interrupt is generated after a delayed branch instruction or interrupt-
disabled instruction, it is sometimes not accepted immediately but stored instead, as shown in
table 5.9. When this happens, it will be accepted when an instruction that can accept the exception
is decoded.
Table 5.9
Notes: 1. Delayed branch instructions: JMP, JSR, BRA, BSR, RTS, RTE, BF/S, BT/S, BSRF,
5.6.1
When an instruction placed immediately after a delayed branch instruction (delay slot) is decoded,
neither address errors nor interrupts are accepted. The delayed branch instruction and the
instruction located immediately after it (delay slot) are always executed consecutively, so no
exception processing occurs during this period.
5.6.2
When an instruction immediately following an interrupt-disabled instruction is decoded, interrupts
are not accepted. Address errors are accepted.
