"The physical HCI interface used by the network processor (HostTestRelease) has
been enhanced to work while power management is enabled on the CC254x device.
The UART interface, when using RTS and CTS lines, can be used by an
external application processor to wake-up the CC254x network processor. When
the network processor has completed all processing, it will go into deep
sleep. In addition to UART, an SPI interface has been added as an option for
the physical HCI interface. It also supports power management by means of
the MRDY and SRDY lines."
Dear,
Where can I find information about the use of the SPI interface (CLK polarity, ...) and MRDY and SRDY lines? At this point I could only find information about the NPI UART configuration in the supplied code (from HostTestRealease project).
