iswritable

Purpose Determine whether MATLAB softw are can write to speciﬁed memory

block

Note Support for iswritable(rx,'channel') on C5000 and C6000

processors will be removed in a future version.

Syntax iswritable(cc,address,'datatype’,count)

iswritable(cc,address,

'datatype')

iswritable(rx,'channel')

Description iswritable(cc,address,'datatype’,count) returns 1 if MATLAB

software can write to the m emory block deﬁned by the

address, count,

and

datatype input arguments on the p rocess or referred to by cc.When

the processor cannot write to any portion of the speciﬁed memory block,

iswritable returns 0. You use the same memory block speciﬁcation for

this function as you use for the write function.

The data b lock being tested begins at the mem ory location deﬁned by

address. count determines the number of values to write. datatype

deﬁnes the format of data stored in the m emory block. iswritable

uses the datatype parameter to d etermine the number of bytes to

write per stored value. For details about each input parameter, read

the following descriptions.

address — iswritable uses address to deﬁne the beginning of the

memory block to write to. You provide values for

address as either

decimal or hexadecimal representations of a mem ory location in the

processor. The full address at a memory location consists of two parts:

the offset and the memory page, entered as a vector [

location, page], a

string, or a decimal value. When the processor has only one memory

page, as is true for many digital signal processors, the page portion

of the memory address is 0. B y default,

ticcs sets the page to 0 at

creation if you omit the page property as an i nput argument.
