I'm still having trouble getting my MSP430F2617 to work with an external 16 MHz oscillator. Thanks for the earlier comments. The MSP430F261x and 241x data sheet(SLAS541K) indicate the ability to use an external oscillator. Does anyone have sample code
The processor is an 80 pin MSP430F2617
The following is sample code that produces 16MHz on SMCLK (pin49) and 112KHz on MCLK (pin48)
int main(void)
{
static int i, j, k, n, dac;
WDTCTL = WDTPW | WDTHOLD; // Stop watchdog timer
// set master clock to external 16.000 MHz oscillator
P8DIR = 0x00; // P8.7 is the 16.00 MHz osc input
P8SEL |= 0x80; // ditto
BCSCTL1 = 0xc0; // XT2 is used for MCLK
BCSCTL3 = 0xf0;
for ( i = 0; i < 5000; i++ ); // short delay
BCSCTL2 = 0x88; // use XT2 clock
......
}
