/* DEVICE
-
+
pal - glue logic device containing assorted junk
-
+
DESCRIPTION
-
+
Typical hardware dependant hack. This device allows the firmware
to gain access to all the things the firmware needs (but the OS
doesn't).
RESET (write): halts the simulator. The value written to the
register is used as an exit status.
-
+
PROCESSOR ID (read): returns the processor identifier (0 .. N-1) of
the processor performing the read.
-
+
INTERRUPT (write): This register must be written using a two byte
store. The low byte specifies a port and the upper byte specifies
the a level. LEVEL is driven on the specified port. By
