Description

TXOP

Ethernet transmit data positive output.[2]

Differential transmit signal pair.

TXON

Ethernet transmit data negative output.[2]

Differential transmit signal pair.

RTC_XIO

Output from the RTC Oscillator amplifier.

RTC_XI/RTC_CLKIN

32.768-kHz clock frequency input to the RTC Oscillator circuit or to

internal RTC clock generator circuit.

VBAT

+1.5V RTC supply voltage.

ADC1/RTC_REF/

CAM_XCLK/GPIO6

I/O

GPIO6 input/output. (By default is GPIO input, internal pull-low)

Camera external clock output.

Reference clock for RTC calibration.

10-bit A/D converter 1, input.

ADC2/CAM_PCLK/GPIO7

I/O

GPIO7 input/output. (By default is GPIO input, internal pull-low)

Camera pixel clock input.

10-bit A/D converter 2, input.

ADC3/CAM_VD/GPIO8

I/O

GPIO8 input/output. (By default is GPIO input, internal pull-low)

Camera vertical sync input.

10-bit A/D converter 3, input.

ADC4/CAM_HD/GPIO9

I/O

GPIO9 input/output. (By default is GPIO input, internal pull-low)

Camera horizontal reference input.

10-bit A/D converter 4, input.

ADC5/CAM_D7/GPIO10

I/O

GPIO10 input/output. (By default is GPIO input, internal pull-low)

Camera data 7 input.

10-bit A/D converter 5, input.

ADC6/CAM_D6/GPIO11

I/O
