23.4.2.5. Direct Mode using SPI or nIRQ Pins
It is possible to use the EZRadioPRO Serial Interface signals and nIRQ as the modulation clock and data.
The MISO signal can be configured to be the data clock by programming trclk = 10. If the NSS signal is
LOW then the function of the MISO signal will be SPI data output. If the NSS signal is high and trclk[1:0] is
10 then during RX and TX modes the data clock will be available on the MISO signal. If trclk[1:0] is set to
11 and no interrupts are enabled in registers 05 or 06h, then the nIRQ pin can also be used as the TX/RX
data clock.
Note: The MISO and NSS signals are internal connections. The nIRQ signal is accessed through an
external package pin.
The MOSI signal can be configured to be the data source in both RX and TX modes if dtmod[1:0] = 01. In
a similar fashion, if NSS is LOW the MOSI signal will function as SPI data-in. If NSS is HIGH then in TX
