µPD750008 USER'S MANUAL
The column of interrupt priority in Table 6-1 indicates a priority assigned when multiple interrupt requests
occur concurrently or are held.
A vector table contains interrupt processing start addresses and MBE and RBE setting values during
interrupt processing. An assembler pseudo instruction (VENTn) is used to set a vector table.
Example A vector table is set for INTBT/INT4.
VENT1 MBE = 0, RBE = 0, GOTOBT

Caution The vector table specified by VENTn (n = 1 to 6) is located at address 2n.
Example Vector tables are set for INTBT/INT4 and INTT0.
VENT1 MBE = 0, RBE = 0, GOTOBT
VENT5 MBE = 0, RBE = 1, GOTOT0
