3.3.2.12.Read IC Version (Code 7
hex
)
With this command the version of the IC is read in two
16 bit words. The first word
n
= n3,n2,n1,n0 contains
the IC’s major number (one nibble for each digit). The
second word (
d
= d3,d2,d1,d0) returns the version as
shown in Table 3–6.
Example:
Read the version information for MAS 35x9F, derivate
0, order version B2:
<DW 68 70 00
<DW 69 <DR
35 09
01 02
>
send version command
and read
MAS 3509F
derivate 0, version B2
(see Section 2.2. on page 8)
3.3.3. List of DSP Registers
The PSelect_Shadow register in Table 3–7 is used to
switch four RAM areas from data to program usage
and thus enabling the DSP’s program counter to
access downloaded program code stored at these
locations. For normal operation (firmware in ROM),
this register must be kept to zero.
Note:
DSP registers not given in Table 3–7 must not
be written.
3.3.4. List of DSP Memory Cells
Among the user interface control memory cells there
are some which have a global meaning and some
which control application specific parts of the DSP
core. In Table 3–8 and Table 3–9, this is reflected by
the key words All, MPEG, and G.729.
