To use vectors specified in the table, the user must insert the address of the

interrupt service routine during code initialization into the pseudo interrupt

table. For an example, for the IRQ vector, the following is performed:

Example: IRQ Service routine label = IRQ_SRV

Ram Vector Table address is defined – RIV_TBL EQU $600

Place IRQ service routine address in the table –

MOVW #IRQ_SRV,RIV_TBL+$32

After debug and the user application is to be programmed for stand alone

operation without the Monitor, the actual interrupt vector table should be added

and the ram vector table loading deleted.
