registers:
The SPI is connected to external devices through four pins:

Functional description
A basic example of interconnections between a single master and a single slave is
illustrated in
The MOSI pins are connected together and the MISO pins are connected together. In this
way data is transferred serially between master and slave (most significant bit first).

SPI Data Register (SPIDR)
MISO: Master In / Slave Out data
MOSI: Master Out / Slave In data
SCK: Serial Clock out by SPI masters and input by SPI slaves
SS: Slave select: This input signal acts as a ‘chip select’ to let the SPI master
communicate with slaves individually and to avoid contention on the data lines.
Slave SS inputs can be driven by standard I/O ports on the master MCU.
