8-Bit Flash MCU with Op Amps & Comparators
· Location 008H
This vector is used by the external interrupt 1. If the external interrupt pin receives an active edge,
the program will jump to this location and begin execution if the external interrupt is enabled and the
stack is not full.
· Location 00CH
This internal vector is used by the Timer/Event Counter 0. If a Timer/Event Counter 0 overflow
occurs, the program will jump to this location and begin execution if the timer/event counter
interrupt is enabled and the stack is not full.
· Location 010H
This internal vector is used by the Timer/Event Counter 1. If a Timer/Event Counter 1 overflow
occurs, the program will jump to this location and begin execution if the timer/event counter
interrupt is enabled and the stack is not full.
· Location 014H
This internal vector is used by the SPI/I²C interrupt. When either an SPI or I²C bus, dependent upon
which one is selected, requires data transfer, the program will jump to this location and begin
execution if the SPI/I²C interrupt is enabled and the stack is not full.
· Location 018H
This internal vector is used by the Multi-function Interrupt. When the Time Base overflows, the A/D
converter completes its conversion process, an active edge appears on the External Peripheral
interrupt pin, a Comparator output interrupt, an EEPROM Write or Read cycle ends interrupt, or a
LVD detection interrupt, the program will jump to this location and begin execution if the relevant
interrupt is enabled and the stack is not full.
