Rev 4.6

SENSOR TIMING GENERATION

The WM8232 provides two types of clock internally. C_CK* are high speed clocks, these clocks can

set the clock phase by using fine pitch phase control. P_CK* are pixel rate signals which is selected

by PO0 to PO7. The WM8232 has eleven sensor TG outputs pins. CLK1 is for clock type use only.

CLK2, CLK3, CLK4, CLK5 and CLK6 are selectable high speed type signal or pulse type signal.

CLK7, CLK8, CLK9, CLK10 and CLK11 are pulse type use only.
