I have the msp430f169 controller. I have a LFXT12768hz, ACLK=LFXT1CLK/8 and MCLK=SMCLK=UCLK0CLK. BCSCTL1 |= XT2OFF + DIVA_3; BCSCTL2 = 0; TACCTL2 = CM_1 + CCIS_1 + CAP; TACTL = TASSEL_2 + MC_2 + TACLR; CCIS_1 define the CCI2B as input signal for capture. What is CCI2B signal? Best regards, MFER

Look on the Port definitions chapter of the data sheet, or family user
guide, there are pictures of the various inputs and outputs for the
timers for each micro.

Thanx Al, but I don't understand if CCI2B is an internal or external
signal.
I've seen the example in the TI website, to generate a stable
MCLKCLK48576hz corrected using the LFXT12768hz:
BCSCTL1 |= XT2OFF + DIVA_3;
BCSCTL2 = 0;
TACCTL2 = CM_1 + CCIS_1 + CAP;
TACTL = TASSEL_2 + MC_2 + TACLR;
// Set_DCO needs to be called to configure DCO
// Target DCO = DELTA*(4096) = 1048576
while (1)
{
while (!(CCIFG & CCTL2));
CCTL2 &= ~CCIFG;
Compare = TACCR2;
Compare = Compare - Oldcapture;
Oldcapture = TACCR2;
if (DELTA == Compare)
{
break; // Break loop
}
else if (DELTA < Compare)
{
DCOCTL--;
if (DCOCTL == 0xFF)
{
if (BCSCTL1 & 0x07)
BCSCTL1--;
else
break;
}
}
else
{
DCOCTL++;
if (DCOCTL == 0x00)
{
if ((BCSCTL1 & 0x07) != 0x07)
BCSCTL1++;
else
break;
}
}
}
CCTL2 = 0; // Stop CCR2
TACTL = 0; // Stop Timer_A
}
in this example:
Is the capture used for acquire the LFXT1?
or need I an external input to generate capture events?
thank you.
best regards,
Marco

CCI2B means input B of the possible inputs to the particular timer B
channel, it could be an internal or an external signal. The diagram in
the ports section of the manual will show you this, as will the hardware
diagram of Timer B. Got to SLAS368, the tech data sheet for the 169,
page 26 in the Oct 2002 version. This clearly shows that both CCIxA and
CCIxB are pins P4.x.
Cheers

Dear marcoferrari72,
is msp430f169 released from TI?
if relesed tell me the cost details of the same.

Hi Venkat, as you can see in the TI website there is no release for msp430f169. I have to ask to my distributors to have a confirm. I'll tell you something in a few days. bye, mfer --- In msp430@msp4..., Venkateswarlu Palle <venkatmsp430@y...> wrote: > Dear marcoferrari72, > > is msp430f169 released from TI? > if relesed tell me the cost details of the same. > > > Venkat > > > > > > > > onestone <onestone@b...> wrote:Look on the Port definitions chapter of the data sheet, or family user > guide, there are pictures of the various inputs and outputs for the > timers for each micro. > > Al > > marcoferrari72 wrote: > > > I have the msp430f169 controller. > > > > I have a LFXT12768hz, ACLK=LFXT1CLK/8 and MCLK=SMCLK=UCLK0CLK. > > > > BCSCTL1 |= XT2OFF + DIVA_3; > > BCSCTL2 = 0; > > TACCTL2 = CM_1 + CCIS_1 + CAP; > > TACTL = TASSEL_2 + MC_2 + TACLR; > > > > CCIS_1 define the CCI2B as input signal for capture.

What I need to know is if CCI2B is connected with ACLK. I'm using Timer_A for Reference Frequency Measurement as shown in the SLAA074 - page 3. In the MSP430x11x there is an internal connection from ACLK and CCI2B (see for example msp430f1132.pdf - page 14). Is there the same connection in the msp430f169?
