Transmit Byte Count Low (XBCL)
Access: write
Together with XBCH (bits XBC11 … XBC8) this register is used in DMA mode only, to
program the length (1 … 4096 bytes) of the next frame to be transmitted. In terms of the
value xbc, programmed in XBC11 … XBC0 (xbc = 0 … 4095), the length of the block in
number of bytes is:
This allows the ESCC2 to request the correct amount of DMA cycles after an XTF or XIF
command in CMDR.
Received Byte Count High (RBCH)
Access: read
