TMDS181: about the EyeScan Tool of TMDS181

Masazumi-san

This field is reflection of register 0x0Fh.

When the pattern verification function is first enabled it will attempt to train to the incoming data pattern. During this training process, incoming data is collected into an internal pattern comparator/generator so as to initialize its pattern state and the pv_tip output is asserted high. When enough data has been collected to initialize the pattern comparator, the pv_tip output is deasserted, the internal pattern comparator runs autonomously, and pattern verification begins. When a mismatch between the incoming data and the expected pattern occurs, the pv_fail output is asserted. If the number of consecutive failures exceeds the threshold specified by the pv_thr input control bus, then the training process is restarted.
