A Transmit Error (Slave mode) is detected, when a transfer was initiated by the master
(shift clock gets active), but the transmit buffer SSCxTB of the slave was not updated
since the last transfer. This condition sets the error flag SSCxTE and, when enabled via
SSCxTEN, the error interrupt request flag SSCxEIR. If a transfer starts while the transmit
buffer is not updated, the slave will shift out the 'old' contents of the shift register, which
normally is the data received during the last transfer.
This may lead to the corruption of the data on the transmit/receive line in half-duplex
mode (open drain configuration), if this slave is not selected for transmission. This mode
requires that slaves not selected for transmission only shift out ones, ie. their transmit
buffers must be loaded with 'FFFF
Note: A slave with push/pull output drivers, which is not selected for transmission, will

normally have its output drivers switched. However, in order to avoid possible
conflicts or misinterpretations, it is recommended to always load the slave's
transmit buffer prior to any transfer.
