Bit 4—Reserved: This bit cannot be modified and is always read as 1.
Bits 3 to 0—Receive Counter (RXCR3 to RXCR0): These bits indicate the received data bit.
Their value is incremented on the fall of KCLK. These bits cannot be modified.
The receive counter is initialized to 0000 by a reset and when 0 is written in KBE. Its value returns
to 0000 after a stop bit is received.
