Register 18: UART 9-Bit Self Address (UART9BITADDR), offset 0x0A4
The UART9BITADDR register is used to write the specific address that should be matched with the
receiving byte when the 9-bit Address Mask (UART9BITAMASK) is set to 0xFF. This register is
used in conjunction with UART9BITAMASK to form a match for address-byte received.

UART0 base: 0x4000.C000
UART1 base: 0x4000.D000
UART2 base: 0x4000.E000
UART3 base: 0x4000.F000
UART4 base: 0x4001.0000

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.
