Description

VDD 1.8V.

I2C DATA pin, the pin can be DFC0 function by pin 3 SEL_DFC power on latch status.

I2C CLK pin, SEL_DFC is a latch input pin during the power-up.

High on power-on: I2C mode as SCLK function.

Low on power-on: pin 3 SCL and pin 2 SDA as DFC function control pins.

Crystal oscillator interface output.

Crystal oscillator interface input or single-ended clock input pin (CLKIN).

Power supply pin for 32.768kHz DCO; usually connect to coin cell battery, 1.8V.

No connection.

1.8V reference clock output.

VDD 1.8V.

Output enable control 2, multi-function pin. Refer to OE function table.
