can you read or write 8 bits at once?

I stand corrected. Thank you for that clarification.
I feel silly for not verifying it first. I'm so used to gcc (been using it since the late 80's)
I forget to check on what the real standard supports.
Kind of odd that there is no support for binary literals in ANSI C.
Oddly enough in over 30 years of embedded C programming I have yet to ever
use binary literals.
