Interrupt system
8.1
80/239
Table 41.
Hardware traps are exceptions or error conditions that arise during run-time. They cause
immediate non-maskable system reaction similar to a standard interrupt service (branching
to a dedicated vector table location).
The occurrence of a hardware trap is additionally signified by an individual bit in the trap flag
register (TFR). Except when another higher prioritized trap service is in progress, a
hardware trap will interrupt any other program execution. Hardware trap services cannot not
be interrupted by standard interrupt or by PEC interrupts.
X-Peripheral interrupt
The limited number of X-Bus interrupt lines of the present ST10 architecture, imposes some
constraints on the implementation of the new functionality. In particular, the additional X-
Peripherals SSC1, ASC1, I
and PEC transfer capabilities. For this reason, a multiplexed structure for the interrupt
management is proposed. In the next
diagram, which shows the basic structure replicated for each of the four X-interrupt available
vectors (XP0INT, XP1INT, XP2INT and XP3INT).
It is based on a set of 16-bit registers XIRxSEL (x=0,1,2,3), divided in two portions each:
●
●
When different sources submit an interrupt request, the enable bits (Byte High of XIRxSEL
register) define a mask which controls which sources will be associated with the unique
