8.3.3
When the BL bit in SR is 0, exceptions and interrupts are accepted.
When the BL bit in SR is 1 and an exception other than a user break is generated, the CPU's
internal registers and the registers of the other modules are set to their states following a manual
reset, and the CPU branches to the same address as in a reset (H'A000 0000). For the operation in
the event of a user break, see section 31, User Break Controller (UBC). If an ordinary interrupt
occurs, the interrupt request is held pending and is accepted after the BL bit has been cleared to 0
by software. If a nonmaskable interrupt (NMI) occurs, it can be held pending or accepted
according to the setting made by software.
Thus, normally, SPC and SSR are saved and then the BL bit in SR is cleared to 0, to enable
multiple exception state acceptance.
8.3.4
The RTE instruction is used to return from exception handling. When the RTE instruction is
executed, the SPC contents are restored to PC and the SSR contents to SR, and the CPU returns
from the exception handling routine by branching to the SPC address. If SPC and SSR were saved
to external memory, set the BL bit in SR to 1 before restoring the SPC and SSR contents and
issuing the RTE instruction.
