Continuous Transfers
When the transmit interrupt request flag is set, it indicates that the transmit buffer SSCTB
is empty and ready to be loaded with the next transmit data. If SSCTB has been reloaded
by the time the current transmission is finished, the data is immediately transferred to the
shift register and the next transmission will start without any additional delay. On the data
line there is no gap between the two successive frames. Eg. two byte transfers would
look the same as one word transfer. This feature can be used to interface with devices
which can operate with or require more than 16 data bits per transfer. It is just a matter
of software, how long a total data frame length can be. This option can also be used eg.
to interface to byte-wide and word-wide devices on the same serial bus.
Note: Of course, this can only happen in multiples of the selected basic data width, since
Master
it would require disabling/enabling of the SSC to reprogram the basic data width
on-the-fly.
