Interrupt Control Functions in the PSW
The Processor Status Word (PSW) is functionally divided into 2 parts: the lower byte of
the PSW basically represents the arithmetic status of the CPU, the upper byte of the
PSW controls the interrupt system of the INCA-D and the arbitration mechanism for the
external bus interface.
Note: Pipeline effects have to be considered when enabling/disabling interrupt requests
serviced by an interrupt service routine. No PECC register is associated and no
COUNT field is checked.
