3.2.1 ControlCARD Configuration

Every controlCARD has switches installed for configuring different pin assignments and other connections on the board. For proper operation these switches have to be configured correctly before inserting the controlCARD to the TIDA-010231 board and powering up. Table 3-3 shows the configurations for the TMS320F280049C controlCARD TMDSCNCD280049C. Up and down and right and left position are referred to the orientation where the HSEC connector of the control card is oriented downwards.

Table 3-3 TMDSCNCD280049C Switch Configuration
SWITCH SETTING COMMENT
S1:A Switch 1 ON, switch 2 OFF Enable USB JTAG and disable USB UART
S1 (installed with 180-degree rotation) Switch 1 and switch 2 up position Select Flash or USB boot mode
S2 Up position Connect GPIO 10 to HSEC pin 60
S3 (installed with 180-degree rotation) Down position Connect GPIO 8 to HSEC pin 58
S4 Down position Use standard 4-pin JTAG
S5 (installed with 180-degree rotation) Switch 1 and switch 2 up position Connect GPIO 25 to HSEC pin 77 and connect GPIO 24 to HSEC pin 75
S6 Switch 1 and switch 2 down position Connect GPIO 26 to HSEC pin 79 and connect GPIO 27 to HSEC pin 81
S7 All switches in the up position Connect internal ADC to HSEC Connector
S8 (installed with 90-degree rotation) Switch 1 and 2 left position Use internal voltage reference for all internal ADCs. Only applicable for use of internal ADCs.
