SYNOPSIS |
|
||||||||||||||||||||||||||||||||||||||||||||||||
FUNCTION | Immediate data is moved to SR. PC is set to next instruction, and the processor stops fetch and execution of instruction. Execution restarts if if a TRACE exception, an interruption, or a RESET takes place. When STOP is executed, a TRACE exception is generated (if T = 1). An interruption is allowed if it level is higher than current one. An external RESET always will generate a RESET exception. If bit S is set to zero by the immediate data, execution of this instruction will generate a "privilege violation". | ||||||||||||||||||||||||||||||||||||||||||||||||
