(2) HALT mode release
The HALT mode can be released by the following two sources.
(a) Release by unmasked interrupt request
When an unmasked interrupt request is generated, the HALT mode is released. If interrupt
acknowledgment is enabled, vectored interrupt servicing is carried out. If interrupt acknowledgment is
disabled, the next address instruction is executed.
Remarks 1. The broken lines indicate the case when the interrupt request which has released the
