It also lists the priorities of trap service for cases, where more than one trap condition might be detected within the same instruction. After any reset (hardware reset, software reset instruction SRST, or reset by watchdog timer overflow) program execution starts at the reset vector at location 00’0000 H. Reset conditions have priority over every other system activity and therefore have the highest priority (trap priority III). Software traps may be initiated to any vector location between 00’0000 H and 00’01FCH. A service routine entered via a software TRAP instruction is always executed on the current CPU priority level which is indicated in bit field ILVL in register PSW. This means that routines entered via the software TRAP instruction can be interrupted by all hardware traps or higher level interrupt requests.
