Hi,

In the DRV870Q1 EVM , what is difference between PH/EN control interface mode and standard PWM control interface mode?

Please explain clearly

    Hi Vasanth,

    Please refer to datasheet Table 3 (PH and EN Control) and Table 5 (Standard PWM Control) for the differences.

    1.i saw datasheet ..but i found same operation is carrying in mode0 and mode hi-z..thats why i asked querry...



    2.i changed source code (according to you mentioned) to generate square wave alternating wave at the output terminal of DRV8703q1 evm...

    Please verify the code and correct me,suggest the changes to generate the square wave alternating wave.(since i dont have launch pad of MSP430g2553, i ordered it,it will take time)

    P2SEL |= EN_IN2;
    TA1CTL = TASSEL_2 | MC_0 | TACLR;
    TA1CCTL0 = CCIE;
    TA1CCTL1 = OUTMOD_7;// The output is reset when the timer counts to the TA1CCR1 value. It is set when the timer
    counts to the TACCR0 value.
    TA1CCTL2 = OUTMOD_3;// The output is set when the timer counts to the TA1CCR2 value. It is reset when the timer
    counts to the TACCR0 value.
    TA1CCR0 = 40000; // 20MSEC PWM period;
    TA1CCR1 = 19900; // 10m sec on
    TA1CCR2 = 19900; // 10m sec off
