Register 0x070: DLL Delay Tap Status
The DLL Delay Tap Status Register indicates the delay tap used by the DLL to generate the
outgoing clock.
Writing to this register performs a software reset of the DLL. A software reset requires a maximum
of 24*256 DLLSYSCLK cycles for the DLL to regain lock. During this time the DLLDCLKO
phase is adjusting from its current position to delay tap 0 and back to a lock position.
TAP[7:0]
The tap status register bits (TAP[7:0]) specifies the delay line tap the DLL is using to generate
the outgoing clock DLLDCLKO.
When TAP[7:0] is logic zero, the DLL is using the delay line tap with minimum phase delay.
When TAP[7:0] is equal to 255, the DLL is using the delay line tap with maximum phase delay.
TAP[7:0] is invalid when vernier enable VERN_EN is set to one.
