Bit 5
Manual Selection Bit (CVS): Selects whether the REF30 signal is generated synchrously
with VD or it is operated in free-run state in the manual mode (VNA = 0). (This selection is
ignored in PB mode except in TBC mode.)
Bit 5
CVS
Description
0
Synchronous with VD
(Initial value)
1
Free-run operation
Bit 4
External Signals Sync Selection Bit (REX): Selects whether the REF30 signal is
generated synchronously with VD, in free-run state or synchronously with the external signal.
(Valid in both PB and REC modes.)
Bit 4
REX
Description
0
VD signal or free-run
(Initial value)
1
Synchronous with external signal
Bit 3
DVCFG2 Sync Selection Bit (CRD): Selects whether the reset timing in the CREF signal
generation is immediately after switching the mode or it is synchronous with the DVCFG2 signal
immediately after the mode switching.
Bit 3
CRD
Description
0
On switching the mode
(Initial value)
1
Synchronous with DVCFG2 signal
Bit 2
ODD/EVEN Edge Switching Selection Bit (OD/EV): Selects whether the REF30P signal
is generated by the rising edge (even) or falling edge (odd) of the field signal in REC mode.
Bit 2
OD/EV
Description
0
Generated at the rising edge of the field signal
(Initial value)
1
Generated at the falling edge of the field signal
