19.6.1.6 Interrupt Status Register 3
19.6.2 Reset
19.6.3 Break Interrupts
MC68HC908GR8 — Rev 4.0
MOTOROLA
Address:
Bits 7–2 — Always read 0
I16–I15 — Interrupt Flags 16–15
All reset sources always have equal and highest priority and cannot be
arbitrated.
The break module can stop normal program flow at a software-
programmable break point by asserting its break interrupt output. See
Timer Interface Module
by forcing it to the SWI vector location. Refer to the break interrupt
subsection of each module to see how each module is affected by the
break state.
