20.5.2
To terminate a slave mode data transfer, after setting SSICR.EN to 0, supply the SSI_WS signal at
the active level (alternate continuous input at the high or low level for the system word length)
until SSICR.IDST becomes 1 (for five or more system words). If the SSI_WS signal is stopped
before IDST becomes 1, the SSI module will not be able to correctly terminate the transfer and
will stop in the transfer interrupted state. If SSICR.EN is set to 1 from this state, incorrect data
may be transmitted due to restarting from the interrupted state. Note that to restart the data
transfer, if the module is in the IDST = 1 state, it can be restarted from the first or second WS edge
from EN = 1.
