It's big endian on big endian architectures.
As far as the FPC compiler is concerned, this should not be a
concern as it
seems the decisions regarding the byte order was made and cemented
in place
long ago. But now that you guys mention byte order, are there
directives in
FPC where integer byte orders can be changed?
No, it's always the native byte order of the underlying architecture.
If language syntax might be extended to provide bit width
accessibility for
MCU's, i think the same methods must be followed throughout FPC: In
all
technical specifications I have come accross, bit 0 is always the
least
significant bit of any word regardless the size of the word. That
makes
things simple.
At least in the PowerPC documentation (both from Motorola and IBM),
bit 0 is always the most significant bit.
