Resets and Interrupts
ILAD — Illegal Address Reset Bit
MODRST — Monitor Mode Entry Module Reset Bit
LVI — Low-Voltage Inhibit Reset Bit
14.3 Interrupts
An interrupt temporarily changes the sequence of program execution to respond to a particular event. An
interrupt does not stop the operation of the instruction being executed, but begins when the current
instruction completes its operation.
14.3.1 Effects
An interrupt:
172
•
•
•
1 = Last reset caused by an opcode fetch from an illegal address
0 = POR or read of SRSR since any reset
1 = Last reset caused by forced monitor mode entry.
0 = POR or read of SRSR since any reset
1 = Last reset caused by low-power supply voltage
0 = POR or read of SRSR since any reset
Saves the CPU registers on the stack. At the end of the interrupt, the RTI instruction recovers the
CPU registers from the stack so that normal processing can resume.
Sets the interrupt mask (I bit) to prevent additional interrupts. Once an interrupt is latched, no other
interrupt can take precedence, regardless of its priority.
Loads the program counter with a user-defined vector address
