Bit 1 CALEN: DLL Calibration Enable
This bit enables the periodic DLL calibration, as per CALRTE[1:0] bit setting. When CALEN bit is
reset, the calibration can be started in single-shot mode with CAL bit.
0: Periodic calibration disabled
1: Calibration is performed periodically, as per CALRTE[1:0] setting
Note: CALEN must not be set simultaneously with CAL bit
Bit 0 CAL: DLL Calibration Start
This bit starts the DLL calibration process. It is write-only.
0: No calibration request
1: Calibration start
Note: CAL must not be set simultaneously with CALEN bit
