RESET:
This field selects the bus monitor time-out period. Refer to Table D-8.
PICR sets the interrupt level and vector number for the periodic interrupt timer (PIT).
Bits [10:0] can be read or written at any time. Bits [15:11] are unimplemented and al-
ways read zero.
This field determines the priority of periodic interrupt requests. A value of %000
disables PIT interrupts.
0 = Halt monitor is disabled.
1 = Halt monitor is enabled.
0 = Disable bus monitor for internal to external bus cycle.
1 = Enable bus monitor for internal to external bus cycle.
