SFR is the framing pulse. Although CE words are always 32 bits, the SSI interface will frame the entire data block as a single
field, as multiple 16-bit fields, or as multiple 32-bit fields. The SFR pulse is one SCLK clock cycle wide, changes state on the
rising edge of SCLK and precedes the first bit of each field.
