AT89S8253 Include

David Lewis

I'm having to upgrade some sources from the obsolete AT89S8252 to the 253.

I'm having trouble though working out the inlude file to use in the project. At first glance it seems to be the "REG8253.H" file which states in its header that it is for this chip.

However, in the datasheet for the 253, it states that the watchdog functions now use WDTCON and not the WMCON of the 252.

But this 253 header file still lists WMCON and not WDTCON

So, what include file should I be using, and is this include file actually wrong?

Or am I missing something somewhere?
