I'm confused about the pins to use to connect the DA14586 to an external device (MSP430) for booting from a serial interface (I'd like to use an SPI interface).
I read AN-B-001 "Booting from serial interfaces" and saw that the booting pin assignments (step 1/SPI Master) were P0_0/SCK, P0_3/CS, P0_5/MOSI, and P0_6/MISO. That seems clear enough, but something I read in the DA14586 datasheet has me confused. The datasheet says that "During the boot sequence, the four SPI pins of port P2 are used to access the internal Flash memory" (P2_0/CLK, P2_3/EN, P2_4/DO, P2_9/DI). This sounds a little like the same thing to me. Is the datasheet telling me about a different function?
Once I've booted the DA14586 using the serial interface I'd like to control the DA14586 using the same SPI interface. Is that possible?
