Notes
- Commands 0x15 and 0x16 are fixed length block read and write commands
for old DCT boards. The ZPDs ignore these commands.
- Command 0x14 (Reframe) resets the Digital Clock Managers (DCMs). The TSF
uses this command to reframe the glink connection.
- Command 0x1e (UserReset) resets state machines and counters.
