Transmit Address Register
TAR | This field is an address matching filed during Transmit mode. If UART_LCR_EXT[DLS_E] bit is enabled, then UART will send the 9-bit character with 9^th bit set to 1 and remaining 8-bit address will be sent from this field provided UART_LCR_EXT[SEND_ADDR] bit set to 1. This field is used only to send the address. The normal data should be sent by programming UART_THR[THR] field. Once the address starts to be send on the UART serial lane, then UART_LCR_EXT[SEND_ADDR] bit will be auto-cleared. |
