How can get PWM output at P2.6 of msp430g2553

  • Table 21 in the datasheet.
  • Hi,

    just take this code as an example.

     *
     * MSP430 code examples are self-contained low-level programs that typically
     * demonstrate a single peripheral function or device feature in a highly
     * concise manner. For this the code may rely on the device's power-on default
     * register values and settings such as the clock configuration and care must
     * be taken when combining code from several examples to avoid potential side
     * effects. Also see www.ti.com/grace for a GUI- and www.ti.com/msp430ware
     * for an API functional library-approach to peripheral configuration.

    //
    //  Description: This program generates one PWM output on P1.2 using
    //  Timer_A configured for up/down mode. The value in CCR0, 128, defines the
    //  PWM period/2 and the value in CCR1 the PWM duty cycle. Using
    //  32kHz ACLK as TACLK, the timer period is 7.8ms with a 75% duty cycle on
    //  P1.2. Normal operating mode is LPM3.
    //  ACLK = TACLK = LFXT1 = 32768Hz, MCLK = default DCO
    //  //* External watch crystal installed on XIN XOUT is required for ACLK *//
