DIP SWITCH SETTINGS
Using the hardware interface feature of the DS2148, the DS2148DK will operate in full hardware mode.
While in hardware mode, S1, S2, and SW1-SW3 are all used in initializing and controlling the DS2148.
For SW1-SW3, the “off” position opens the switch while “on” closes the switch, grounding the attached
device pin. See the DS2148 data sheet for details on the function of each pin.
S1 selects 3V or 5V mode.
S2 selects the 2.048MHz or 1.544MHz oscillator.
SW1-SW3 are listed in Table 2
