Note: Vector number is used by the SetUserVector function to set up the interrupt vector.

Mnemonic names for D-Bug12 RAM interrupt-vector addresses
It is very simple to set up the SRAM interrupt vector. Assuming that the service routine
for the IRQ interrupt starts with the label
irqISR
, then one of the following two methods can be
used to establish the SRAM table entry for the IRQ interrupt:
Method 1
org
$3E72
; one can also use “org UserIRQ”
dc.w
irqISR
Method 2
ldd
#irqISR
std
$3E72
; one can also use “std UserIRQ”
