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;
