Q: FAQ: Strobe command SPI timing for CC110x/CC1150/CC2500/CC2550 by 611949

A Strobe command can be issued immediately after the preceeding Strobe command, provided that the preceeding Strobe command
has been completely transfered over the SPI interface. However, note that for SPI clock speed above 6.5 MHz, the CC110x SPI interface
requires a certain delay between each SPI byte transfer (see the respective Data Sheets).
