31:8 RO 24'b0 RSRV (RSRV)
7:0 RW 8'h0 TAR (TAR)
This is an address matching
register during transmit mode.
If DLS_E (LCR[8]) bit is
enabled, then the UART
Controller will send the 9-bit
character with 9-th bit set to 1
and remaining 8-bit address
will be sent from this register
provided 'SEND_ADDR'
(LCR[10]) bit is set to 1.
NOTE:
1. This register is used only to
send the address. The normal
data should be sent by
programming THR register.
2. Once the address is started
to send on the UART Controller
serial lane, then SEND_ADDR
bit will be auto-cleared by the
hardware.
