3.4 EVM Configuration DIP Switch

Common processor board has dedicated EVM configuration switch (SW3) shown in Figure 3-4 to set the various functions of EVM peripherals. The Configuration DIP Switch (SW3) is placed on Top side of CPB right below the USB Type C port.

This switch includes configuration options for the expansion board. EVM Board ID EEPROM Write Protect function and Motor Control/Boosterpack Mux selection is defined by EVM Configuration DIP Switch SW3 Bit 9 and 8, respectively, as described in Table 3-1.

Table 3-1 EVM Configuration Switch Function
Switch Name Default Condition Signal Operation
SW3.8 ON INFO_CAM_VIO_SEL ‘0’ (OFF) = PWM Signals connects to “Motor Control Header”
‘1’ (ON) = PWM Signals connects to “Boosterpack Header”
SW3.9 ON BOARDID_EEPROM_WP Sets EVM’s configuration EEPROM Write Protection
‘0’ (OFF) = Configuration EEPROM can be updated
1’ (ON) = Configuration EEPROM cannot be updated/protected
