Like the iswritable, write,andread functions, isreadable checks
for valid address values. Illegal address values would be any address
space larger than the available space for the processor – 2
32
for the
C6xxx processor family and 2
16
for the C5xxx series. When the function
identifies an illegal address, it returns an error m essage stating that
theaddressvaluesareoutofrange.
isreadable(cc,address,'datatype') returns 1 if the processor
referred to by
cc can read the memory block defined by the address,
and
datatype input arguments. When the processor cannot read a ny
portion of the specified memory block,
isreadable returns 0. Notice
that you use the same mem ory block specification for this function as
you use for the read function. The data block being tested begins at the
memory location defined by
address. When you omit the count option,
count defaults to one.
isreadable(rx,'channel') returns a 1 when the RTDX channel
specified by the string
channel, associated with link rx,isconfigured
for
read operation. When channel is not configured for reading,
isreadable returns 0.
Like the
iswritable, read,andwrite functions, isreadable checks for
valid address values. Illegal address values are address spaces larger
