20.3.2.1
Read: Anytime, if AMAP = 0. If only SCIBDH is written to, a read will not return the correct data until
SCIBDL is written to as well, following a write to SCIBDH.
Write: Anytime, if AMAP = 0.
The SCI baud rate register is used by to determine the baud rate of the SCI, and to control the infrared
modulation/demodulation submodule.
Freescale Semiconductor
1.These registers are accessible if the AMAP bit in the SCISR2 register is set to zero.
2,These registers are accessible if the AMAP bit in the SCISR2 register is set to one.
