read
defaults to a value of 1. This syntax reads one memory location of
datatype.
Note To ensure seamless read operatio n, use address to extract
address values that are compatible with the alignment required by your
processor.
read does not force data type alignment in your processor
memory.
Certain combinations of address and datatype are difficult for some
processors to use. To ensure seamless
read operation, use the address
function to extract address values that are com patible with the
alignment required by your processor.
Like the
isreadable, iswritable,andwrite functions, read checks
for valid a ddress values. Illegal a ddress values are any addre s s s p ace

values are out of range.
