13706PLAY Diagnostic Utility S1D13706
Issue Date: 01/02/23 X31B-B-003-02
Commands
The following commands are designed to be used from within the 13706PLAY program.
However, simple commands can also be executed from the command line. If a command
with multiple arguments is executed from the command line, it must be enclosed in double
quotes (e.g. 13706play “f 0 14000 AB” q).
Note
If the endian mode of the host platform is big endian, reading/writing words and dwords
to/from the registers and display buffer may be incorrect. It may be necessary for the
user to manually swap the bytes in order to perform the IO correctly. For further infor-
mation on little/big endian and the S1D13706 byte/word swapping capabilities, see the
S1D13706 Hardware Functional Specification, document number X31B-A-001-xx.
CLKI [?] iFreq
Selects a preset clock frequency (MHz) for CLKI. If the “?” option is used, the list of
available frequencies for CLKI is displayed.
Where:
? Displays a list of available frequencies for CLKI (MHz).
iFreq Sets CLKI to an index representing a preset frequency
(MHz) specified by iFreq. iFreq is based on the table
provided with the command CLKI ?.
Note
The CLKI command programs preset frequencies available on the S5U13706B00C
evaluation board. This function is not designed for use on other evaluation platforms or
prototype designs.
CLKI2 [?] iFreq
Selects a preset clock frequency (MHz) for CLKI2. If the “?” option is used, the list of
available frequencies for CLKI2 is displayed.
Where:
? Displays a list of available frequencies for CLKI2 (MHz).
iFreq Sets CLKI2 to an index representing a preset frequency
(MHz) specified by iFreq. iFreq is based on the table
provided with the command CLKI2 ?.
Note
The CLKI2 command programs preset frequencies available on the S5U13706B00C
evaluation board. This function is not designed for use on other evaluation platforms or
prototype designs.
CW word
Sends a 24-bit hexadecimal value to the programmable clock. Note that the programmable
clock documentation uses the term “word” to describe the 24-bit value. The use of “word”
does not imply a 16-bit value in this case.
