Serial Clock:
 SCLK: SCK
Master Output → Slave Input (MOSI):
 SIMO, MTSR - correspond to MOSI on both master and slave devices, connects
to each other
 SDI, DI, DIN, SI - on slave devices; connects to MOSI on master, or to below
connections
 SDO, DO, DOUT, SO - on master devices; connects to MOSI on slave, or to
above connections
Master Input ← Slave Output (MISO):
 SOMI, MRST - correspond to MISO on both master and slave devices, connects
to each other
 SDO, DO, DOUT, SO - on slave devices; connects to MISO on master, or to
below connections
 SDI, DI, DIN, SI - on master devices; connects to MISO on slave, or to above
connections
Slave Select:
 SS: SS, SSEL, CS, CS, CE, nSS, /SS, SS#
In other words, MOSI (or SDO on a master) connects to MOSI (or SDI on a slave).
MISO (or SDI on a master) connects to MISO (or SDO on a slave). Slave Select is
the same functionality as chip select and is used instead of an addressing concept.
Pin names are always capitalized as in Slave Select, Serial Clock, and Master Output
Slave Input.
