22. EZRadioPRO Serial Interface (SPI1)
The EZRadioPRO serial interface (SPI1) provides access to the EZRadioPRO peripheral registers from
software executing on the MCU core. The serial interface consists of two SPI peripherals—a dedicated SPI
Master accessible from the MCU core and dedicated SPI Slave residing inside the EZRadioPRO periph-
eral. The SPI1 peripheral on the MCU core side can only be used in master mode to communicate with the
EZRadioPRO slave device in three wire mode. NSS for the EZRadioPRO is provided using Port 1.3, which
is internally routed to the EZRadioPRO peripheral. The EZRadioPRO Serial Interface provides a system
interrupt to regulate SPI traffic between the MCU core and the EZRadioPRO peripheral. This interrupt is
internally routed to the MCU core. The EZRadioPRO peripheral also has an nIRQ pin which should be
routed external to the package back into an external interrupt pin. The nIRQ interrupt pin is independent of
the EZRadioPRO Serial Interface.
