0.3VDD

Magnification

NTSC mode: 63.5µs, PAL mode: 63.9µs

SEN logic level is to be High for this period.

0.3VDD

Note) During the 1H period for generating XSG1, the phase against AVD differs according to each mode.

Please always maintain the SEN logic level at High for "the 1H period when XSG1 varies."
