The RXACCM registers define received characters in the range 00–1F as mapped (Control bit set)
or not mapped (Control bit clear) as follows:
RXACCM0 bits 0–7 control characters 00–07, respectively.
RXACCM1 bits 0–7 control characters 08–0F, respectively.
RXACCM2 bits 0–7 control characters 10–17, respectively.
RXACCM3 bits 0–7 control characters 18–1F, respectively.
