Modules§

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).
OVRDEN
Slave clock delay line delay cell number selection override enable.
OVRDVAL
Slave clock delay line delay cell number selection override value.
SLVDLYTARGET
The delay target for slave delay line is: ((SLVDLYTARGET+1) * 1/32 * clock cycle of reference clock (serial root clock). If serial root clock is >= 100 MHz, DLLEN set to 0x1, OVRDEN set to =0x0, then SLVDLYTARGET setting of 0xF is recommended.
