iRAM_EnH: When 1, MOVX will access internal 1KB SRAM

dis_exint: When 1, disable external interrupt

clr_exint: When 1, clear external interrupts, then have to clear to 0

clr_inint: When 1, clear internal interrupts, then have to clear to 0

{Mode1, Mode0}:

{0, 0} = Normal capture mode.

{0, 1} = Compressed capture mode (DPCM).

{1, 0} = Full window display on LCM mode (through P0).

{1, 1} = Hardware windowing display on LCM mode (through P0).

{skip1, skip0}:

{0, 0} = No skip pixel when display on LCM

{0, 1} = Skip 1 pixel when display on LCM

{1, 0} = Skip 2 pixel when display on LCM

{1, 1} = Skip 4 pixel when display on LCM

intp_pd: When 1, disable interrupt block, 0 enable interrupt block.

lcdwrb: Control output pin LCD_WRB.

SDAo: I2C data output of sensor.

int4lcd: During LCD mode, each frame will generate interrupt called int4lcd.

int4cap: When set Capture at Cap register and ASIC finish its capture job. ASIC will

generate interrupt called int4cap.

CSB: When 1, disable sensor, 0 enable sensor
