Interrupt system
The interrupt response time for internal program execution is from 125ns to 300ns at 40MHz
CPU clock.
The ST10F280 architecture supports several mechanisms for fast and flexible response to
service requests that can be generated from various sources (internal or external) to the
microcontroller. Any of these interrupt requests can be serviced 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 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 ST10F280 has 8 PEC channels,
each of them offers such fast interrupt-driven data transfer capabilities.
An 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.
Software interrupts are supported by means of the ‘TRAP’ instruction in combination with an
individual trap (interrupt) number.
