3.1.1 Configuration
3.1.1.1 INTERNAL DEFAULT CONFIGURATIONS WITH STRAPPING OPTIONS
Upon power-up, the UPD301A uses internal default register settings. The controls are
configured by selecting one of the six resistor values for each pin. EVB-UPD301A
demonstrates three of the six possible resistor values for each profile. These straps are
sensed by the UPD301A device at power-on to determine the resultant configuration
of the device. To select the preferred configuration, shunts must be connected to J11
and J12 headers (refer to
Table 3-1 ).
Note: The VID, PID, and DID, and additional settings are configured using the
internal ROM code.
