RX_FULL

RX_POINTER
Reserved
BIF

PEF
RS485_ADD_DETF
Reserved
RX_OVER_IF
UA_THR, TX_POINTER increases one. When one byte of TX FIFO is transferred to
Transmitter Shift Register, TX_POINTER decreases one.
Receiver FIFO Full (Read Only)
This bit initiates RX FIFO full or not.
This bit is set when RX_POINTER is equal to 64/16(UART0/UART1), otherwise is
cleared by hardware.
Receiver FIFO Empty (Read Only)
This bit initiate RX FIFO empty or not.
When the last byte of RX FIFO has been read by CPU, hardware sets this bit high. It
will be cleared when UART receives any new data.
RX FIFO Pointer (Read Only)
This field indicates the RX FIFO Buffer Pointer. When UART receives one byte from
external device, RX_POINTER increases one. When one byte of RX FIFO is read by
CPU, RX_POINTER decreases one.
Reserved
Break Interrupt Flag (Read Only)
This bit is set to a logic 1 whenever the received data input(RX) is held in the
“spacing state” (logic 0) for longer than a full word transmission time (that is, the total
time of “start bit” + data bits + parity + stop bits) and is reset whenever the CPU
writes 1 to this bit.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
Framing Error Flag (Read Only)
This bit is set to logic 1 whenever the received character does not have a valid “stop
bit” (that is, the stop bit following the last data bit or parity bit is detected as a logic 0),
and is reset whenever the CPU writes 1 to this bit.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
Parity Error Flag (Read Only)
This bit is set to logic 1 whenever the received character does not have a valid “parity
bit”, and is reset whenever the CPU writes 1 to this bit.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
RS-485 Address Byte Detection Flag (Read Only)
This bit is set to logic 1 and set UA_ALT_CSR [RS-485_ADD_EN] whenever in RS-
485 mode the receiver detect any address byte received address byte character (bit9
= ‘1’) bit", and it is reset whenever the CPU writes 1 to this bit.
Note: This field is used for RS-485 function mode.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
Reserved
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 bytes of UART0/UART1, this bit will be set.
Note: This bit is read only, but can be cleared by writing ‘1’ to it.
