Address
0x0048
HSIZE (width) register and VSIZE register (height) control the size of the output images.
HSTART register and VSTART register control the readout start position ,the address
is shown in Table 13.The default of HSIZE is 0x780，The default of VSIZE is 0x438，
the size of the default image is 1920x1080. After HSIZE，VSIZE，HSTART and
VSTART are wrote , 0x001d register need to write 0x01 or 0x02

Bit[1] reserved
Bit[0] mclk option:
1: make mclk equal to clkin
0: make mclk equal to the
fractional
mean Fmclk = Fpclk/(mclkc+1)。
F indicate the Corresponding to
the clock frequency.
