Note:

TPR=292 x 4 x TCLK. TCLK is internal pixel period. TCLK=112ns if the system clock is 17.73MHz. TCLK will

increase with the clock divider CLK[5:0].

TEX is array exposure time which is decided by external master device.

TIN is uncertain time due to the using of HSYNC rising edge to synchronize FREX. TIN < THS.

There are 8 lines data output before valid data after FREX=0. THD=4 THS. Valid data is output when

HREF=1.

TSET=TIN + TPR + TEX. TSET > TPR + TIN. The exposure time setting resolution is THS (one line) due to the

uncertainty of TIN.
