System Event Routing
Additional system events are routed to each of the C64x+ Megamodules to provide chip-level events that
are not required as CPU interrupts/exceptions to be routed to the interrupt controller as emulation events.
Additionally, error-class events or infrequently used events are also routed through the system event
router to offload the C64x+ Megamodule interrupt selector. This is accomplished through Chip Interrupt
Controllers, CIC[2:0], with one controller per C64x+ Megamodule. This is clocked using CPU/6.
The event controllers consist of simple combination logic to provide sixteen events to each C64x+
Megamodule, plus the TPCC.
These events are routed to the C64x+ Megamodules for AET purposes, from those TPCC and FSYNC
events that are not otherwise provided to each C64x+ Megamodule. The event controllers each include
two event combiners to provide two combined events to each C64x+ Megamodule, for use. Each of the 16
event outputs from the controllers can select any of the 64 inputs, or either of the two combined events to
pass on to their respective C64x+ Megamodule.
Table 7-15
lists the system events that are available to each C64x+ Megamodule through their respective
event controllers. Note that n implies the event number matches the C64x+ Megamodule number to which
it is routed.
