Interrupts caused by the address matching detection and when di-
viding by zero are software interrupts and are not included in Figure
14.
Other interrupts previously mentioned are A-D converter, UART, etc.
interrupts. The priority of these interrupts can be changed by chang-
ing the priority level in the corresponding interrupt control register by
software.
Figure 15 shows a diagram of the interrupt priority detection circuit.
When an interrupt is caused, each interrupt device compares its own
priority with the priority from above and if its own priority is higher,
then it sends the priority below and requests the interrupt. If the pri-
orities are the same, the one above has priority.
This comparison is repeated to select the interrupt with the highest
priority among the interrupts that are being requested. Finally the
selected interrupt is compared with the processor interrupt priority
level (IPL) contained in the processor status register (PS) and the
request is accepted if it is higher than IPL and the interrupt disable
flag I is
“
0
”
. The request is not accepted if flag I is
“
1
”
. The reset and
watchdog timer interrupts are not affected by the interrupt disable
flag I.
When an interrupt is accepted, the contents of the processor status
register (PS) is saved to the stack and the interrupt disable flag I is
set to
“
1
”
.
Furthermore, the interrupt request bit of the accepted interrupt is
cleared to
“
0
”
and the processor interrupt priority level (IPL) in the
