2.2. Connector Pin List
2.3. Host interfaces
It provides the support of the following host interfaces:
I2C-bus Slave Interface, up to 3.4 Mbaud
SPI-bus Slave Interface, up to 7 Mbaud
Only one host interface can be active at same time as pins are shared for all interfaces. The
selection between interfaces is fused during IC manufacturing so that different ordering
numbers for the I2C-bus, SPI-bus version.
The host interfaces are woken-up in the following way:
Wake-up with WKUP_REQ input pin
I2C-bus: wake-up on I2C-bus address
SPI-bus: transition of NSS serial
