USER’S MANUAL

5.8 Interrupts

Interrupt recognition and servicing involve complex interaction between the SIM, the
CPU16, and a device or module requesting interrupt service. This discussion provides
an overview of the entire interrupt process. Chip-select logic can also be used to re-
spond to interrupt requests. Refer to

5.9 Chip-Selects

 for more information.

5.8.1 Interrupt Exception Processing

The CPU16 handles interrupts as a type of asynchronous exception. An exception is
an event that preempts normal processing. Exception processing makes the transition
from normal instruction execution to execution of a routine that deals with an excep-
tion. Each exception has an assigned vector that points to an associated handler rou-
tine. These vectors are stored in a vector table located in the first 512 bytes of address
bank 0. The CPU16 uses vector numbers to calculate displacement into the table. Re-
fer to

4.13 Exceptions

 for more information.

5.8.2 Interrupt Priority and Recognition

The CPU16 provides for seven levels of interrupt priority (1 – 7), seven automatic in-
terrupt vectors, and 200 assignable interrupt vectors. All interrupts with priorities less
than seven can be masked by the interrupt priority (IP) field in the condition code
register.

There are seven interrupt request signals (IRQ[7:1]). These signals are used internally
on the IMB, and there are corresponding pins for external interrupt service requests.
The CPU16 treats all interrupt requests as though they come from internal modules;
external interrupt requests are treated as interrupt service requests from the SIM.
Each of the interrupt request signals corresponds to an interrupt priority level. IRQ1
has the lowest priority and IRQ7 the highest.

The IP field consists of three bits (CCR[7:5]). Binary values %000 to %111 provide
eight priority masks. Masks prevent an interrupt request of a priority less than or equal
to the mask value (except for IRQ7) from being recognized and processed. When IP
contains %000, no interrupt is masked. During exception processing, the IP field is set
to the priority of the interrupt being serviced.

Interrupt recognition is determined by interrupt priority level and interrupt priority (IP)
mask value. The interrupt priority mask consists of three bits in the CPU16 condition
code register (CCR[7:5]). Binary values %000 to %111 provide eight priority masks.
Masks prevent an interrupt request of a priority less than or equal to the mask value
from being recognized and processed. IRQ7, however, is always recognized, even if
the mask value is %111.

IRQ[7:1] are active-low level-sensitive inputs. The low on the pin must remain asserted
until an interrupt acknowledge cycle corresponding to that level is detected.

IRQ7 is transition-sensitive as well as level-sensitive: a level-7 interrupt is not detected
unless a falling edge transition is detected on the IRQ7 line. This prevents redundant
servicing and stack overflow. A non-maskable interrupt is generated each time IRQ7
is asserted as well as each time the priority mask is written while IRQ7 is asserted. If
IRQ7 is asserted and the IP mask is written to any new value (including %111), IRQ7
will be recognized as a new IRQ7.
