3.13 Multi Vector Control
3.13.1 Multi Vector Controller
(1) Outline
By rewriting the value of multi vector control register (MVEC0 and MVEC1), a
vector table is arbitrarily movable.
(2) Control register
The amount of 228 bytes become an interruption vector area from the value set as
vector control register (MVEC0 and MVEC1).
