Read the MSP430 Programmers Guide. That will answer your questions.

Re: Can any plz explain this - Alexander Espinosa - Sep 3 14:54:15 2008
Hi, you need to read the=A0 datasheet for your microcontroller.
you'll see the meaning for each register there, including use of pins for A=
DC converter and use of other peripherals....
=A0
=20=20=20=20=20=20

Re: Can any plz explain this - Tom Baugh - Sep 3 15:33:22 2008
Nav,
I think a great place to start to help understanding that sample
program is to read the new book, MSP430 Microcontroller Basics, by
John Davies:
http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%
2Fwww.amazon.com%2FMSP430-Microcontroller-Basics-John-Davies%2Fdp%
2F0750682760%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1220014595%26sr%3D8-
2&tag=softcom-20&linkCode=ur2&camp=1789&creative=9325
After that book, you will then be ready to use the state-based
approach that we have used with the MSP430 world for a decade. This
approach is provided in detail in our book MSP430 State Machine
Programming:
http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%
2Fwww.amazon.com%2FMSP430-State-Machine-Programming-ES2274%2Fdp%
2F0975475924%3Fie%3DUTF8%26s%3Dbooks%26qid%3D1214397954%26sr%3D8-
1&tag=softcom-20&linkCode=ur2&camp=1789&creative=9325
If those links don't work, then search amazon.com for MSP430 as one
word. John's book and ours will be at the top of the list. The pair
of these books, studied intently for a few weeks, will fill in a lot
of the gaps. Also, after working the exercises in our book you will
have a level of architectural expertise that would otherwise take
years to learn. This is like taking a MSP430 course in a few weeks
for less than $100.
You can find reviews of our book elsewhere on this group, but let me
know if you have any questions.

While I do appreciate the advice that you put forth on the mailing list
and I do value your experience and knowledge, the continuing
self-promotion is starting to wear thin. In the case below, you do not
actually offer advice but instead just ask people to buy your book. It
is one thing to suggest a book once or twice. I think there were three
cases today alone where you recommended buying the book without actually
offering advice.
Respectfully
Dan

You seem to have a stuck-key problem with your keyboard. I suggest you get a can of air and give your keyboard a good blow.

Hi,
The WatchDog module can be configured as either a watchdog or a
interval timer,WDT_MDLY_32 provides 32ms interval.
If you are using IAR embedded system,you can find the watchdog timer
definition in the .h header files
C:\Program Files\IAR Systems\Embedded Workbench 5.0\430\inc
If need to learn MSP430,go through the online training.
