Register 0x1037: DLL RUL3 Control Status
The DLL Control Status Register provides information of the DLL operation.
RUN:
ERROR:
ERRORI:
RFCLKI:
The DLL lock status register bit RUN indicates the DLL has found an initial lock condition.
When the phase detector first indicates lock, RUN is set high. The RUN register bit is
cleared only by a system reset or a software reset.
The delay line error register ERROR indicates the DLL is currently at the end of the delay
line. ERROR is set high when the DLL tries to move beyond the end of the delay line.
Once DLL is in ERROR state, the only way to restore the DLL into normal operational state
is to reset DLLs.
The error event register bit ERRORI indicates the ERROR register bit has been a logic one.
When the ERROR register changes from a logic zero to a logic one, the ERRORI register
bit is set to logic one. The ERRORI register bit is cleared immediately after it is read, thus
acknowledging the event has been recorded.
The clock event register bit RFCLKI provides a method to monitor activity on the RFCLK
clock. When the RFCLK input changes from a logic zero to a logic one, the RFCLKI
register bit is set to logic one. The RFCLKI register bit is cleared immediately after it is
read, thus acknowledging the event has been recorded.
