5.4 INTERRUPTS
The ST6 core may be interrupted by four maska-
ble interrupt sources, in addition to a Non Maska-
ble Interrupt (NMI) source. The interrupt process-
ing flowchart is shown in
Maskable interrupts must be enabled by setting
the GEN bit in the IOR register. However, even if
they are disabled (GEN bit = 0), interrupt events
are latched and may be processed as soon as the
GEN bit is set.
Each source is associated with a specific Interrupt
Vector, located in Program space (see
the vector location, the user must write a Jump in-

struction to the associated interrupt service rou-
tine.
When an interrupt source generates an interrupt
request, the PC register is loaded with the address
of the interrupt vector, which then causes a Jump
to the relevant interrupt service routine, thus serv-
icing the interrupt.
Interrupt are triggered by events either on external
pins, or from the on-chip peripherals. Several
events can be ORed on the same interrupt vector.
On-chip peripherals have flag registers to deter-
mine which event triggered the interrupt.
