Bit Description

7Reserved

6INT_INVERT

R/W

If set to “1” the INT pin output is inverted. This applies to

all output signals as selected in INT_PINMAP

5INT_IN_EN

R/W

If programmed to “1” the INT pin is set as input. Please

observe that the connected net must not be floating

since INT is an open drain input.

INT_IN

External HIGH or LOW value applied to INT pin

3VSYNC_GPIO_INVERT

R/W

If set to “1” the VSYNC/GPIO pin output is inverted. This

applies to all output signals as selected in VSYNC_GPIO_

PINMAP

VSYNC_GPIO_IN_EN

R/W

If programmed to “1” the VSYNC/GPIO pin is set as

input. Please observe that the connected net must not

be floating since VSYNC/GPIO is an open drain input

VSYNC_GPIO_OUT

R/W

Programs the VSYNC/GPIO pin HI or LOW. Since the pin

is an open drain I/O pin, the default value is HIGH to

avoid any unintended power consumption through

pull-up resistor. The routed internal signal is selected in

VSYNC_GPIO_PINMAP.

VSYNC_GPIO_IN

External HIGH or LOW value applied to VSYNC/GPIO pin.
