8.2.5
During each instruction cycle one out of all sources which require PEC or interrupt
processing is selected according to its interrupt priority. This priority of interrupts and
PEC requests is programmable in two levels. Each requesting source can be assigned
to a specific priority. A second level (called “group priority”) allows to specify an internal
order for simultaneous requests from a group of different sources on the same priority
level. At the end of each instruction cycle the one source request with the highest current
priority will be determined by the interrupt system. This request will then be serviced, if
its priority is higher than the current CPU priority in register PSW.
8.2.6
Interrupt processing is controlled globally by register PSW through a general interrupt
enable bit (IEN) and the CPU priority field (ILVL). Additionally the different interrupt
sources are controlled individually by their specific interrupt control registers (...IC).
Thus, the acceptance of requests by the CPU is determined by both the individual
interrupt control registers and the PSW. PEC services are controlled by the respective
PECCx register and the source and destination pointers, which specify the task of the
respective PEC service channel.
