NRM … Normal Response Mode
Note:
Transmit Byte Count High (WRITE)
Value after RESET: 000xxxxx
XBCH
DMA … DMA Mode
XC … Transmit Continuously
CAS … Carrier Detect Auto Start
Semiconductor Group
XBC11 … XBC8 … Transmit Byte Count (most significant bits)
Valid in auto-mode only! Use in auto-mode only; reset this bit in non auto-mode, transparent
mode, and extended transparent mode.
Determines the function of the LAP controller:
0 … full-duplex LAPB/LAPD operation
1 … half-duplex NRM operation
Selects the data transfer mode of HSCX to system memory.
0 … Interrupt controlled data transfer (interrupt mode)
1 … DMA controlled data transfer (DMA Mode)
Only valid if DMA mode is selected!
If the XC bit is set, the HSCX continuously requests for transmit data ignoring the transmit
byte count programmed via XBCH, XBCL.
When set, a high at the CD (A CLK) pin enables the respective receiver and data reception
is started.
Valid only if DMA mode is selected!
Together with XBC7 … XBC0 the length of the frame to be programmed.
CAS has to be "0" for clock mode 1 and 5
