Fujitsu F2MC-8FX manual Program Area, Callv Jump Address Table

CHAPTER 2 MEMORY SPACE

2.2.2Program Area

The program area in the F2MC-8FX CPU includes the following two:

•Vector call instruction table

•Reset and interrupt vector table

■Vector Call Instruction Table

FFC0H to FFCFH of the memory space is used as the vector call instruction table. The vector call

instruction for the F2MC-8FX CPU provides access to this area according to the vector numbers included in the OP code and makes a subroutine call using the data written there as the jump address. Table 2.2-2indicates the correspondence of the vector numbers with the jump address table.

Table 2.2-2 CALLV Jump Address Table

CALLV	Jump address table
#k	Upper address	Lower address
#0	FFC0H	FFC1H
#1	FFC2H	FFC3H
#2	FFC4H	FFC5H
#3	FFC6H	FFC7H
#4	FFC8H	FFC9H
#5	FFCAH	FFCBH
#6	FFCCH	FFCDH
#7	FFCEH	FFCFH

■Reset and Interrupt Vector Table

FFCCH to FFFFH of the memory space is used as the table indicating the starting address of an interrupt or reset Table 2.2-3indicates the correspondence between the interrupt numbers or resets and the reference

table.
