8 - INTERRUPT SYSTEM
The interrupt response time for internal program
execution is from 157ns to 375ns at 32MHz CPU
clock.
The ST10F168 architecture supports several
mechanisms for fast and flexible response to ser-
vice requests that can be generated from various
sources (internal or external) to the microcontrol-
ler. Any of these interrupt requests can be ser-
viced by the Interrupt Controller or by the
Peripheral Event Controller (PEC).
In contrast to a standard interrupt service where
the current program execution is suspended and
a branch to the interrupt vector table is performed,
just one cycle is ‘stolen’ from the current CPU
activity to perform a PEC service. A PEC service
implies a single Byte or Word data transfer
between any two memory locations with an
additional increment of either the PEC source or
the destination pointer. An individual PEC transfer
counter is implicitly decremented for each PEC
service except when performing in the continuous
transfer mode. When this counter reaches zero, a
standard
interrupt
is
performed
to
the
corresponding source related vector location.
PEC services are very well suited to perform the
transmission or the reception of blocks of data.
The ST10F168 has 8 PEC channels, each of
them offers such fast interrupt-driven data transfer
capabilities.
A interrupt control register which contains an
interrupt request flag, an interrupt enable flag and
an interrupt priority bitfield is dedicated to each
existing interrupt source. Thanks to its related
register, each source can be programmed to one
of sixteen interrupt priority levels. Once starting to
be processed by the CPU, an interrupt service
can only be interrupted by a higher prioritized
service
request. For
the standard interrupt
processing, each of the possible interrupt sources
has a dedicated vector location.
Fast external interrupt inputs are provided to ser-
vice external
interrupts
with
high
precision
requirements. These fast interrupt inputs feature
programmable edge detection (rising edge, falling
edge or both edges). Software interrupts are sup-
ported by means of the ‘TRAP’ instruction in com-
bination with an individual trap (interrupt) number.
Table 9 shows all the available ST10F168 inter-
rupt
sources
and
the
corresponding
hard-
ware-related
interrupt
flags,
vectors,
vector
locations and trap (interrupt) numbers:
