I have 8051 with 2 DPTR, SFR register to switch data banks(32Kb/16Kb)... Both DPTRs used to increment read/write pointers. I need correct 32bit address increment over all accessible memory. How to widen DPTR to work with 32 bit address?
I would avoid the use of "word" to mean "16 bits"
See: www.8052.com/.../read.phtml
Strictly, on an 8051, the word-size is 8 bits.
Micro$oft wouldn't :)
They currently uses it to mean half (and possibly also a quarter of) the size of an integer register...)
That's because they used it specifically in the context of their original 16-bit platform.
They are now stuck with it for 32- and 64-bit platforms.
Serves 'em right!
