Setup Instructions

SETINT1 {#}D - Configure Interrupt 1

Encoding	Register Written	C Flag	Z Flag	Cycles (cogexec)	Cycles (hubexec)	IRQ Shield

SETINT2 {#}D - Configure Interrupt 2

Encoding	Register Written	C Flag	Z Flag	Cycles (cogexec)	Cycles (hubexec)	IRQ Shield
EEEE 1101011 00L DDDDDDDDD 000100110	none	---	---	2	2	No

SETINT3 {#}D - Configure Interrupt 3

SETINTx configures which Event ID triggers the respective interrupt based on Destination. An event ID of zero (or INT_OFF) disables the interrupt (EVENT_INT is not available).
