AT32UC3A
Pulse length is equal to ({FSLENHI,FSLEN} + 1) Transmit Clock periods, i.e., the pulse length can range from 1 to 16
Transmit Clock periods. If {FSLENHI,FSLEN} is 0, the Transmit Frame Sync signal is generated during one Transmit Clock
period.
• DATNB: Data Number per frame
This field defines the number of data words to be transferred after each transfer start, which is equal to (DATNB +1).
• MSBF: Most Significant Bit First
0: The lowest significant bit of the data register is shifted out first in the bit stream.
1: The most significant bit of the data register is shifted out first in the bit stream.
• DATDEF: Data Default Value
This bit defines the level driven on the TX_DATA pin while out of transmission. Note that if the pin is defined as multi-drive
by the PIO Controller, the pin is enabled only if the SCC TX_DATA output is 1.
• DATLEN: Data Length
0: Forbidden value (1-bit data length not supported).
Any other value: The bit stream contains DATLEN + 1 data bits. Moreover, it defines the transfer size performed by the
PDCA assigned to the Transmit. If DATLEN is lower or equal to 7, data transfers are bytes, if DATLEN is between 8 and 15
(included), half-words are transferred, and for any other value, 32-bit words are transferred.
