HRTIM DLL control register (HRTIM_DLLCR)

Address offset: 0x3CC

Reset value: 0x0000 0000

Bits 31:4 Reserved, must be kept at reset value

Bits 3:2 CALRTE[1:0]: DLL Calibration rate

This defines the DLL calibration periodicity.

00: 1048576 * t

01: 131072 * t

10: 16384 * t

11: 2048 * t

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
