Notes:
1. The sync modes should normally be changed only when the device is in IDLE mode.
2. CODEC sync mode is the default following reset.
3. DATA sync mode is selected automatically during Host-to-Host compression or decompression. This
sync mode will remain in effect until a new sync mode command is issued. Once Host-to-Host
compression has been started (after the C1 command), another sync mode command can be issued to
change to a different sync mode.
4. Select POLL sync mode if TFR_MODE = [binary] 11. Use this mode for DMA and if transferring data
via the Host Transmit/Receive Data Buffer Access Ports.
