O
MPU/USB clock crystal oscillator output pin.
X32IN
8
I
RTC clock crystal oscillator input pin. A 32768Hz
crystal is required for low-power RTC operation.
X32OUT
7
O
RTC clock crystal oscillator output pin.

O
I
2C (master mode) compatible Clock signal. Note: the
pin is configured as an open drain output. When the
I2C interface is being used, an external pull up resistor
is required. A value of 3K is recommended.
SDA

IO
I
2C (master mode) compatible data I/O. Note: this pin is
bi-directional. When the pin is configured as output, it
is an open drain output. When the I2C interface is
being used, an external pull up resistor is required. A
value of 3K is recommended.
