22.4. EZRadioPRO Serial Interface Interrupt Sources
When SPI1 interrupts are enabled, the following flags will generate an interrupt when they are set to logic
1:
All of the following bits must be cleared by software.
22.5. Serial Clock Phase and Polarity
Four combinations of serial clock phase and polarity can be selected using the clock control bits in the SPI
Configuration Register (SPI1CFG). The CKPHA bit (SPI1CFG.5) selects one of two clock phases (edge
used to latch the data). The CKPOL bit (SPI1CFG.4) selects between an active-high or active-low clock.
Both CKPOL and CKPHA must be set to zero in order to communicate with the EZRadioPRO peripheral.
The SPI1 Clock Rate Register (SPI1CKR) as shown in SFR Definition 22.3 controls the master mode
serial clock frequency. When the SPI is configured as a master, the maximum data transfer rate (bits/sec)
is one-half the system clock frequency or 12.5 MHz, whichever is slower.

the MSTENn and SPIENn bits in SPI0CN are set to logic 0 to disable SPIn and allow another
master device to access the bus.
and a transfer is completed and the receive buffer still holds an unread byte from a previous
transfer. The new byte is not transferred to the receive buffer, allowing the previously received
data byte to be read. The data byte which caused the overrun is lost.
