SWAPL (Swap Low Byte): This bit must be set to enable byte swapping. If the bit is
cleared, then byte swapping is disabled.
Reserved for future use.
SWAPH (Swap High Byte): This bit must be set to enable byte swapping. If the bit is
cleared, then byte swapping is disabled.
Reserved for future use.
This 16-bit register is used to control the swapping of the low and high data
bytes when reading or writing with a 16-bit host. This provides an Endian-
independent method of enabling/disabling the byte swap feature.
Note: Hosts that support 8-bit access only do not need to write to this register.
