RS485_ADD_DETF
RS-485 Address Byte Detection Flag (Read Only)
0 = Receiver detects a
data that is not an address bit (bit 9 =’1’).
1 = Receiver detects a data that is an address bit (bit 9 =’1’).
Note1:
This field is used for RS-485 function mode and RS485_ADD_EN
(UA_ALT_CSR[15]) is set to 1 to enable Address detection mode.
Note2:
This
bit is read only, but can be cleared by writing ‘1’ to it.

RX_OVER_IF
RX Overflow Error IF (Read Only)
This bit is set when RX FIFO overflow.
If the number of bytes of received data is greater than RX_FIFO (UA_RBR) size,
64/16/16 bytes of UART0/UART1/UART2, this bit will be set.
0 = RX FIFO is not overflow.
1 = RX FIFO is overflow.
Note:
This bit is read only, but can be cleared by writing “1” to it.
