Hi all,

I am chasing the info for the operation of the memory of the MC145512p 
this is a tone / pulse dialler chip, all the docs I can find, just give 
a block diagram, but do not explain how to use the chip.

This chip is used in my test butt for phone work, but I do not know how 
to use the memories etc on it (I was never told this secret when I 
worked for the telco and none of my friends used the features)

If anyone has more than the one page PDF that is online I would 
appreciate it :)
-- 
Regards,

Kat.

Possibly some extra information on the life-saver site?  :-

If you don't need pulse dialing (does any PTSN not accept DTMF these 
days?), why not just use the DTMF function in Bascom?

It does work quite well....
