The RGB 5:6:5 input format is processed to be displayed as RGB 5:5:5 format, compliant with
the 16-bit mode of the LCD controller.
The sensor master clock (ISI_MCK) can be generated either by the Advanced Power Manage-
ment Controller (APMC) through a Programmable Clock output or by an external oscillator
connected to the sensor.
None of the sensors embeds a power management controller, so providing the clock by the
APMC is a simple and efficient way to control power consumption of the system.
Care must be taken when programming the system clock. The ISI has two clock domains, the
system bus clock and the pixel clock provided by sensor. The two clock domains are not syn-
chronized, but the system clock must be faster than pixel clock.
