Important: To prevent indeterminate system behavior, reserved areas of memory must not be accessed by software or hardware. Any area of the memory map that is not explicitly defined as a register space or accessible memory is considered reserved.

These bits are only valid when FIFO access mode is enabled (FAR[0] is set to one). When FIFO's are enabled, this bit is used to write framing error detection information to the receive FIFO. When FIFO's are not enabled, this bit is used to write framing error detection information to the RBR.

WO 0x0
8 rfpe

These bits are only valid when FIFO access mode is enabled (FAR[0] is set to one). When FIFO's are enabled, this bit is used to write parity error detection information to the receive FIFO. When FIFO's are not enabled, this bit is used to write parity error detection information to the RBR.

7:0 rfwd

These bits are only valid when FIFO access mode is enabled (FAR[0] is set to one). When FIFO's are enabled, the data that is written to the RFWD is pushed into the receive FIFO. Each consecutive write pushes the new data to the next write location in the receive FIFO. When FIFO's are not enabled, the data that is written to the RFWD is pushed into the RBR.
