Those two manuals were my first references to turn to , and the reason wh=
y I=20
went software is because in the Mid-range ref manual, page 248 (design ti=
ps):
"Question 2: Using I2C mode, I do not seem able to make the master mode w=
ork.
Answer: The SSP module does not have the master mode fully automated in=20
hardware. If you require a fully automated hardware implementation of I2C=
=20
MasteR Mode, please refer to the ...."

This seems to indicate that it is not capable - but reading other paragra=
phs=20
in the reference indicates that I2C Master Mode can be implemented. I gue=
ss I=20
got confused and decided to write my own routines - doing so unsuccessful=
ly=20
thusfar. Either way, I cannot find examples of I2C Master Mode=20
initialization/implementation in either manual.
