DLL Control Register 0
| DLLEN | DLL calibration enable. |
| DLLRESET | Software could force a reset on DLL by setting this field to 0x1. This will cause the DLL to lose lock and re-calibrate to detect an ref_clock half period phase shift. The reset action is edge triggered, so software need to clear this bit after set this bit (no delay limitation). |
| SLVDLYTARGET | The delay target for slave delay line is: ((SLVDLYTARGET+1) * 1/32 * clock cycle of reference clock (serial clock). |
| OVRDEN | Slave clock delay line delay cell number selection override enable. |
| OVRDVAL | Slave clock delay line delay cell number selection override value. |
