DMA Mode
Selects the data transfer mode of ESCC2 to/from System
Memory.
0 … Interrupt controlled data transfer (Interrupt Mode).
1 … DMA controlled data transfer (DMA Mode).
Normal Response Mode
Allowed in auto-mode only.
Determines the function of the LAP Controller:
0 … full-duplex LAPB/LAPD operation
1 … half-duplex NRM operation
Carrier Detect Auto Start
When set, a ‘high’ on the CD pin enables the corresponding
receiver and data reception is started. When not set, if not in Clock
Mode 1 or 5, the CD pin can be used as a general input.
Transmit Continuously
Only valid if DMA Mode is selected.
If the XC bit is set, the ESCC2 continuously requests for transmit
data ignoring the transmit byte count programmed via XBCH,
XBCL. The byte count programmed via XBCH, XBCL, however,
must be set to a value different from ‘0’.
Transmit Byte Count (most significant bits)
Valid only if DMA Mode is selected.
Together with XBCL (bits XBC7 … XBC0) these bits determine
the length of the frame to be transmitted.
