*
* $Log: custom_tab.c,v $
* Revision 1.5 1998/02/10 17:20:50 marcus
* Synchronized raster counter.
*
* Revision 1.4 1998/02/10 01:32:12 marcus
* DMACON added.
*
* Revision 1.3 1998/02/10 01:02:00 marcus
* DENISEID register implemented.
*
* Revision 1.2 1996/07/21 16:16:13 grubba
* custom_write_intena() and custom_write_intreq() moved to interrupt.[ch].
* Serialport emulation on stdin/stdout added.
* Custom registers that are write-only are now declared as such.
*
* Revision 1.1 1996/07/19 16:46:12 grubba
* Cleaned up interrupt handling.
* Cleaned up custom chip emulation.
* INTENA/INTREQ should work.
