2.16.4 Clock for OSD
As a clock for display to be used for OSD, it is possible to select one of the following 3 types.
• Data slicer clock output from the data slicer (approximately 26 MHz)
• Clock from the LC oscillator supplied from the pins OSC1 and OSC2
• Clock from the ceramic resonator (or the quartz-crystal oscillator) from the pins OSC1 and OSC2
Note : To use data slicer clock, set bit 0 of data slicer control register 1 to “1.”
