6.2.2.26. TG_SKEW_CAL

Offset: 0x1D0
Default: 0x20
Description: Initial skew calibration length in UI (rounded down to number of PPI access)
Bit Name Access Description
31 TG_SKEW_CAL_INIT_SKEW_UNMASK Read Write

Init skew calibration unmask enable

1 - enable init skew calibration generation after test restart

0 - disable init skew calibration generation after test restart

Note: Under normal operation, init skew is only done on D-PHY link after device TINIT and D-PHY IP automatically does that. This bit enables driving init skew again for testing/debug.
30:0 TG_SKEW_CAL_INIT_SKEW_CAL_LEN Read Write Initial skew calibration transfer length in UIs (lower 3 bits are ignored - rounded down to # of bytes).
