4.2
The registers described in Table 4-2 are used to determine
general configuration for the SC1200/SC1201 processor.
These registers also indicate which multiplexed signals are
issued via balls from which more than one signal may be

Note:
FPCI_MON (Fast-PCI Monitoring). Selects Fast-PCI monitoring output signals instead of Parallel Port signals.
Fast-PCI monitoring output signals can be enabled in two ways: by setting this bit to 1 or by strapping FPCI_MON (ball A4)
high. (The strapped value can be read back at MCR[30].) Listed below is how these two options work together and the sig-
nals that are enabled (enabling overrides add’l dependencies except FPCI_MON = 1). Note that the FPCI monitoring signals
that are muxed with Audio signals are not enabled via this bit. They are only enabled using the strap option.
