If an
I10
bit
is
configured as an output, the number read by test 10 will be the same number that
is
pro-
grammed. If an
I10
bit
is
configured
as
an input, the number read by test 10 will be the input signal level
on the
I10 line. Therefore, if an
I10
port
is
programmed, and then read, the number displayed may not
correspond to the number programmed because some bits of the
I10
port may be configured as inputs.
