Register 16: UART 9-Bit Self Address Mask (UART9BITAMASK), offset 0x0A8
The UART9BITAMASK register is used to enable the address mask for 9-bit mode. The address
bits are masked to create a set of addresses to be matched with the received address byte.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Self Address Mask for 9-Bit Mode
This field contains the address mask that creates a set of addresses
that should be matched.
