| | === External Synchronization === |
| |
| in_voltage0_test_mode:off | The [[resources:fpga:peripherals:jesd204:jesd204_tpl_adc|ADC TPL HDL]] core supports the [[resources:fpga:peripherals:jesd204:jesd204_tpl_adc#External_synchronization|EXT_SYNC]] feature, allowing to synchronize multiple channels within a ADC or across multiple instances. |
| | This feature can also synchronize between the [[resources:fpga:peripherals:jesd204:jesd204_tpl_adc|ADC TPL HDL]] and [[resources:fpga:peripherals:jesd204:jesd204_tpl_dac|DAC TPL HDL]] core. |
| | |
| | There are two device attributes which allows controlling this feature: |
| | ''sync_start_enable'' and ''sync_start_enable_available'' reading the |
| | later returns the available modes which depend on HDL core synthesis |
| | parameters. The options are explained below. Reading 'sync_start_enable' |
| | returns either 'arm' while waiting for the external synchronization |
| | signal or 'disarm' otherwise. |
| | |
| | * ''arm'': Setting this key will arm the trigger mechanism sensitive to an external sync signal. Once the external sync signal goes high it synchronizes channels within a ADC, and across multiple instances. This key has an effect only the EXT_SYNC synthesis parameter is set. |
| | |
| | * ''disarm'': Setting this key will disarm the trigger mechanism sensitive to an external sync signal. This key has an effect only the EXT_SYNC synthesis parameter is set. |
| | |
| | * ''trigger_manual'': Setting this key will issue an external sync event if it is hooked up inside the fabric. This key has an effect only the EXT_SYNC synthesis parameter is set. |
