SPI Serial Clock. The serial shift clock input, which is used to synchronize
serial interface reads and writes.
SPI Serial Data I/O. A dual purpose pin that typically serves as an input or
an output, depending on the instruction being sent and the relative
position in the timing frame.
Chip Select Bar (Active Low). CSB gates the read and write cycles.
Output Enable Bar Input (Active Low).
Power-Down Input (Active High). The operation of this pin depends on
the SPI mode and can be configured as power-down or standby (see
Table 14).
