Controls and Indicators
4.1 DIP Switches
Figure 4-1 shows the locations on the board of the DIP-switches. Table 4-1 describes the
possible settings of the DIP switches. Note that when ON, the value of the switch is zero. For
more detailed descriptions of the bits and fields, see the MSC8144 Reference Manual. Check the
default positions, and verify that the board is operational before changing any settings.
Table 4-2 on page 4 shows default DIP-switch positions when the configuration word is taken
from the I
taken from the EEPROM itself instead of from the DIP switch settings (which are ignored in
these cases). The specific default values are the same as in 4-3, with the following exceptions:
Table 4-1 shows default DIP-switch positions when the reset configuration word is taken from
external pins.
