36.4.2.5 Tap Delays at High Interface Speeds

The SQI module provides a tap control register, TAPCON, which can be used to adjust the timing between the SQICLK and SQID0-SQID3 signals to compensate for the data delays control the setup and hold times at higher speeds. Each tap adds a certain delay on the signal that can be used to control the clock and data relationship, and may be useful in certain instances to compensate for the PCB routing delays. Refer to the Electrical Characteristics for the exact delay that each tap element adds.
