Synchronizable Timecode Generator User Manual 5-10
5.15 Read Version
0 x 00ec
This allows the user to read the version numbers of the FPGA (field-programmable gate array)
and the embedded firmware. It is
not possible to determine what options are present, or which
version is more recent, from this number. It is is for diagnostic purposes only. Spectracom
suggests that the user's software include a means of reading and displaying these
numbers.
Send command 0x000000ec to tbreg_cmd[3]. The FPGA version is reported in bits 23:00 of
tbreg_response[0]. The embedded firmware version is reported in bits 23:00 of
tbreg_response[2]. These are in hexadecimal format.
For example, if the FPGA version is 033000 and the firmware version is 032900, the response
is:
tbreg_response[0] = 0x??033000
tbreg_response[1] = 0x????????
tbreg_response[2] = 0x??032900
tbreg_response[3] = 0x????00ec
5.16 Lamp Test
0 x 00ee
This diagnostic command initiates the same lamp test sequence that occurs during power-on
reset. There is no response. The yellow
ACQ and green SYNC panel lights are illuminated
briefly, one at a time. The In-Sync output on the TIMING connector will be asserted while the
green SYNC panel light is illuminated. Write command 0x000000ee to tbreg_cmd[3].
5.17 Blink Yellow Mode
0 x 00b0 and 0 x 00b1
This diagnostic command blinks the yellow ACQ panel light briefly each time the board finishes
processing any command. If the ACQ indicator is already lit, it will extinguish briefly when a
command is processed. This can be helpful during software debugging. This mode is disabled
when a power-on reset or Forced Reset occurs. There is no response.
Write 0x000000b1 (enable) or 0x000000b0 (disable) to tbreg_cmd[3].
NOTE: This command can also be used to provide a visual cue. For example, the user
software can be written to send the enable command, immediately followed by a
disable command, when a time tag event is detected, when the interrupt handler
routine is entered, or when an external device is ready.
