34 / 54 page MOTOROLA MCM20014 34 The Internal Timing Control Register; Table 28, is used to define the size of internal timing pulse widths. In de- fault, both shs and shr are 6 MCLK’s wide. The user is strongly encouraged to write an 00h to this register; thus making these pulse widths 16 MCLKs wide. 5.5.2 Programmable “Window of Interest” The WOI is defined by a set of registers that indicate the upper-left starting point for the window and another set of registers that define the size of the window. Please refer to Figure 6, on page 7 for a pictorial representation of the WOI within the active pixel array. The WOI Row Pointer; wrp[8:0] (Table 29 and Table 30), and the WOI Column Pointer; wcp[9:0] (Table 31 and Table 32), mark the upper-left starting point for the WOI. The WOI Row Pointer; wrp[8:0], has a range of 0d to 511d whereas the WOI Column Pointer; wcp[9:0] has a usable range of 0d to 703d. The pointer can be placed anywhere within the active pixel array. The WOI Row Depth; wrd[8:0] (Table 29 and Table 30), and the WOI Column Depth; wcd[9:0] (Table 31 and Table 32), indicate the size of the WOI. The WOI Row Depth; wrd[8:0], has a range of 0d to 511d whereas the WOI Column Depth; wcd[9:0], has a range of 0d to 703d. The user should be careful to create a WOI that con- tains active pixels only. There is no logic in the sensor Address 60h Internal Timing Control Default 66h msb (7) 654321 lsb (0) shs[3] shs[2] shs[1] shs[0] shr[3] shr[2] shr[1] shr[0] Bit Number Function Description Reset State 7 - 4 shs shs[3:0] = 0000b = 16 MCLKs Wide shs[3:0] = 0001b = 1d MCLKs Wide shs[3:0] = 0010b = 2d MCLKs Wide | shs[3:0] = 0110b = 6d MCLKs Wide | shs[3:0] = 1111b = 15d MCLKs Wide 0110b 3 - 0 shr shr[3:0] = 0000b = 16 MCLKs Wide shr[3:0] = 0001b = 1d MCLKs Wide shr[3:0] = 0010b = 2d MCLKs Wide | shr[3:0] = 0110b = 6d MCLKs Wide | shr[3:0] = 1111b = 15d MCLKs Wide 0110b Table 28.
