4.6.11 Vector
This section explains how to display and modify SOFTUNE WORKBENCH vectors.
■ Vector
When the MCU is reset or when an interrupt processing request is issued for a variety of factors, the MCU
sets the data, set in the address determined in advance according to the type of the interrupt, in the PC as
the address of the interrupt processing routine. The address at which this interrupt processing routine is set
is called a vector. Vectors are determined in advance according to the kind of the MCU.
