Transmit Byte Count Low (WRITE)

XBC0
(2A/6A)
Together with XBCH (bits XBC11…XBC8) this register is used in DMA mode only, to program
the length (1…4095 bytes) of the next frame to be transmitted.
This allows the HSCX to request the correct amount of DMA cycles after an XTF or XIF
command via CMDR.
Note: The number of transmitted bytes is XBC + 1, e.g. if the content of XBC is 00 exactly one
byte will be transmitted.

BR7 – BR0…Baudrate, bit 7 - 0
Together with bits BR9, BR8 of CCR2, the division factor of the baudrate generator is adjusted.
Dependent on the programmed value N in BR9 – BR8 (N = 0…1023) the division factor k
results as follows:
k = (N + 1) × 2
