Motor driver PWM signals
CRUVI interface signals are utilized to drive the half bridge PWM motor driver signals. They are logical connected to prevent driving the high and low simultanously:
M_PWM_AH <= '1' when ((A3_N='1') and (A1_P ='0')) else '0';
M_PWM_AL <= '1' when ((A1_P='1') and (A3_N ='0')) else '0';
M_PWM_BH <= '1' when ((A3_P='1') and (A0_P ='0')) else '0';
M_PWM_BL <= '1' when ((A0_P='1') and (A3_P ='0')) else '0';
M_PWM_CH <= '1' when ((A1_N='1') and (A2_N ='0')) else '0';
M_PWM_CL <= '1' when ((A2_N='1') and (A1_N ='0')) else '0';
M_PWM_DH <= '1' when ((A0_N='1') and (A2_P ='0')) else '0';
M_PWM_DL <= '1' when ((A2_P='1') and (A0_N ='0')) else '0';
Motor disable
The M_DISABLE signal set via push button S1 is used to disable all 4 motor drivers. This signal is logical or to the PWM enable signal from B1_P on the CRUVI connector.
M_DISABLE_OUT <= M_DISABLE or not B1_P;
M_DISABLE_A_D <= M_DISABLE_OUT;
M_DISABLE_B_D <= M_DISABLE_OUT;
M_DISABLE_C_D <= M_DISABLE_OUT;
M_DISABLE_D_D <= M_DISABLE_OUT;
The motor disable signal is also forwarded to the CRUVI interface:
A5_P <= M_DISABLE;
Sensor/Encoder, Back EMF
Sensor signals are forwarded to the CRUVI interface:
B2_P <= ENC_A;
B2_N <= ENC_B;
B3_P <= ENC_I;
B3_N <= M_BEMF_B_D;
B4_N <= M_BEMF_A_D;
B4_P <= M_BEMF_C_D;
Current and voltage measurement
Data signals from the 3 ADCs are forwarded to the CRUVI interface:
B5_N <= SD_V;
B5_P <= SD_IA;
A4_P <= SD_IB;
The corresponding clock signals are derived from the CRUVI interface signal B1_N:
SCLK_V_A <= B1_N;
SCLK_A <= B1_N;
Button
Motor disable button
S1 is utilized to switch the motor control on/off. The button is debounced. On press it switches the state of M_DISABLE signal and sets the corresponding LED status.
User Button
User button S2 is forwarded to the CRUVI interface signal A4_N:
A4_N <= BUTTON1;
LEDs
Status LED
The LED D1 is utilized for board status information in the following way:

Level shifting/MUX
In this Firmware Version CRUVI Low Speed connector CA has four signals configured as input and another four as output. Depending on the connectors and signals used/needed this can be changed by customizing and updateing the firmware. Also the 3.3V signals on the three CRUVI High Speed connectors can be utilized in that way. See TEB0707 CPLD Firmware.

JTAG
Switch with hard wired JTAGEN Dip4 between user mode of pins, which corresponds due to the lines below to SoM JTAG ("OFF", open, 'low') and Max10 CPLD ("ON", closed, 'high')
TDO <= M_TDO;
M_TMS <= TMS;
M_TCK <= TCK;
M_TDI <= TDI;
UART
M_G6_01 <= F_UART_TX; --TX UART to SoM
F_UART_RX <= M_G6_02; --RX UART from SoM
Module control pins
RESIN <= BUTTON0; -- reset SoM
NOSEQ <= net_gnd; -- powermanagement by CPLD is NOT disabled
PROGMODE <= not(DIP3); -- select between CPLD (low, closed, on) on SoM or FPGA/SoC (high, open, off )
EN1 <= net_vcc; --module power always enabled
MODE <= SD_CD ; -- select SD boot mode when card installed ('low'), else QSPI ('high')
Button and Dips
User Button
User button on PL is debounced:
M_G1_20 <= Button1_db;
User Dips:
Dip1 is directly forwarded to a PL IO:
M_G1_16 <= not(DIP1);
Dip2 is used for IO Voltage selection, see IO Voltage selection.
Dip3 is used for JTAG selection, see Module control pins.
LEDs
Status LEDs
The LED D7 and D8 are utilized for board status and power information in the following way:

USR LEDs
User LEDs D1, D2, D3 (green) are connected to PL IOs:
LED3 <= M_G1_19;
LED2 <= M_G1_18;
LED1 <= M_G1_17;
User LEDs D4, D5, D6 (red) are connected to IOs which are located at PL or PS depending on SoM.
LED4 <= M_G6_04;
LED5 <= M_G6_07;
LED6 <= M_G6_08;
ETH LEDs
Ethernet Jack LEDs are not used in this firmware and are therefore tied to GND.
ETH_LED2 <= net_gnd;
ETH_LED1 <= net_gnd;
Power sequenzing
The M3.3VOUT signal of the SoM is used to Enable CRUVI power rails and the SOM IO Voltage:
EN_C5VIN <= M3_3VOUT;
EN_C3_3V <= M3_3VOUT;
EN_IOV <= M3_3VOUT;
IO Voltage selection
Select IOV Voltage of DCDC U3:
VS0 <= not(DIP2);
VS1 <= DIP2;
VS2 <= net_gnd;
"010" selects 1.8V (Dip2 open, "OFF", 'high').
"001" selects 2.5V (Dip2 closed, "ON", 'low').
USR LED
User LED D2 is controlled via the CRUVI signal B0_N:
LED0 <= B0_N;
