KBCR2 is a 4-bit counter which performs counting synchronized with the falling edge of KCLK.
Transmit data is synchronized with the transmit counter, and data in the KBTR is sent to the KD
(LSB-first).

Transmit Counter
Indicates bit of transmit data. Counter is incremented
at the falling edge of KCLK. The transmit counter is
initialized by a reset, when the KBTS is cleared to 0,
the KBIOE is cleared to 0, or the KBTE is set to 1.
