Receive Byte Count Low (RBCL)
Access: read
Indicates the number of valid bytes available in the accessible part of the RFIFO. This
register must be read by the CPU following a TCD interrupt. In case of a TCD interrupt
the number of valid bytes in the accessible part of the RFIFO can be evaluated by
‘AND’-ing the contents of RBCL with: threshold level (bytes) – 1.

RBC is reset with RMC after preceding TCD interrupt.
In case of RPF interrupt RBC is incremented by ‘threshold level (bytes)’.
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 data block 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
XF command in CMDR.
