BIT | FIELD | TYPE | DEFAULT | DESCRIPTION |
---|---|---|---|---|
7:0 | LINE_COUNT_LO | R | 0x0 | Low byte of Line Count The Line Count reports the line count for the most recent video frame. When interrupts are enabled for the Line Count (via the IE_LINE_CNT_CHG register bit), the Line Count value is frozen until read. In addition, when reading the LINE_COUNT registers, the LINE_COUNT_LO is latched upon reading LINE_COUNT_HI to ensure consistency between the two portions of the Line Count. |
