on the SPI-4 egress status channel.
synchronization to in synchronization condition interrupt indication enable.
to an unavailable condition interrupt indication enable. SCLK_UN_EN should
be written as a zero if using a SPI-4 egress LVTTL status clock that is less than
one-half of the MCLK frequency. The SCLK_UN_I interrupt indication is not
usable in this case.
