Philips PCF 8591

[skimask]

Check the PBP mqnual. PBP *AUTOMATICALLY* sets the LSbit to the
correct value. That is, the I2CREAD instruction FORCES the bit to "1"
and I2CWRITE FORCES it to "0". Try it in your code, and you will find
that it works.

I know. I was jumping back and forth while typing in my last post, checking the datasheet for the PCF, the manual, I2C spec's, etc. I should've hit refresh before submit!
