Figure 23 - SYNC “0001” Burn Phase 3 Unit Must be Disabled
The user may read the register that was just programmed by clicking on the “SYNC” button. Picor Buck GUI should
show the new burned in values read back from the SYN[3:0] register as shown in Figure 24. If an error message
occurs or the incorrect results are obtained, refer to the section titled “PI33XX-2X Error Messages” for more
information.
Figure 24 - Read SYN[3:0] After Burning “0001”
It is important to note that the data sent here is the value shown in the dialog window. The actual read is the
burned in value of the register. Sending “4Ch 21h FFh” or “4Ch 21h 00h” would also work properly.
