DMA-mode.
Selects the data transfer mode between the SACCO FIFOs and the system
memory:
0…interrupt controlled data transfer (interrupt mode).
1…DMA controlled data transfer (DMA-mode).
Transmit Continuously.
When XC is set the SACCO continuously requests for transmit data ignoring
the transmit byte count programmed in register XBCH and XBCL.
Together with XBC7…XBC0 the length of the next frame to be transmitted in
DMA-mode is determined (1…4096 bytes).
Selects one of up to 64 time-slots (00
clock mode 2. The number of bits per time-slot is programmable in register
XCCR.
Transmit Clock Shift bit2-1.
Together with XCS0 in register CCR2 the transmit clock shift can be
adjusted in clock mode 2.
