[Timer A] Difference between TACLK and INCLK ? - fwolff - Sep 15 9:39:12 2008
Hi,
I was reading the chapter concerning the Timer A and I saw that "the
timer clock can be sourced from ACLK, SMCLK, or externally via TACLK
or INCLK.". I looked in all datasheets but nowhere it is said what's
the difference between TACLK and INCLK (if there is any difference). I
don't see the point of having two external clock sources.
Thanks in advance for your help.
Regards,
Frank.

I have a similar question. Where do TACLK and INCLK come from? They don't seem to have
hardware connections to any pins on the chip package, and I don't see a way to establish a
logical connection either.
I am using the MSP430F2274 and the IAR C Embedded Workbench from the eZ430RF2500 development kit.

TACLK and INCLK (also called TAINCLK) are described in the data-sheet.
Sorry, I am not aware of any c sample code or video about this.

Re: [Timer A] Difference between TACLK and INCLK ? - Hugh Molesworth - Nov 7 15:01:49 2009
Having multiple external clock input pins avoids adding external
hardware for some applications, and allows selective use of other
functions in others; if that isn't a requirement in your design just
ignore the second input and use either input as convenient. On the
MSP430F22x4 TACLK comes from pin 31 on the 38-pin DA package and from
pin 29 on the 40-pin RHA package; TAINCLK (INCLK) comes from pin 9 on
the 38-pin DA package and from pin 7 on the 40-pin RHA package; it's
all in the data sheet SLAS504c.pdf available here:

Thanks, I must have spent an hour searching the data sheet before giving up and finding another way to solve my problem.
