THIS MANUAL IS INCOMPLETE but what is written here should be more accurate and up to date than the old "functional specification". Please e-mail me if you find mistakes/omissions here (Eric H).

TTS Testing

Changed:
<
<
There is a test mode which forces the AMC13 to send a specific 4-bit pattern on the (s)TTS output. For example:   > WV CONF.DIAG.TTS_TEST_ENABLE 1 > WV CONF.TTS_TEST_PATTERN 5
>

There is a test mode which forces the AMC13 to send a specific 4-bit pattern on the (s)TTS output. Note that the AMC13 cannot be in run mode to use this feature and the TTC loop-back feature cannot benabled (since this uses the fiber transmitter normally used for TTS).
 
Changed:
<
<
This would send a binary 0101 (decimal 5) to TTS continuously.
>
>
For example:   > I 1 N    > WV CONF.DIAG.TTS_TEST_ENABLE 1
  > WV CONF.TTS_TEST_PATTERN 5

This would send a binary 0101 (decimal 5) to TTS continuously.
Note the I 1 N command initializes the AMC13 without the "T" option (TTC loopback) and with the "N" option (do not put the AMC13 in run mode).

  The test pattern is at offset 0x19, bits 8-11 and the enable bit is bit 12 at offset 0x1 (on the Virtex chip)
