10.14.2.8 SCIRXBUF Register (Offset = 7h) [reset = 0h]
SCIRXBUF is shown in Figure 10-18 and described in Table 10-14.
Return to the Summary Table.
When the current data received is shifted from RXSHF to the receiver buffer, flag bit RXRDY is set and
the data is ready to be read. If the RXBKINTENA bit (SCICTL2.1) is set, this shift also causes an interrupt.
When SCIRXBUF is read, the RXRDY flag is reset. SCIRXBUF is cleared by a system reset.

Bit Field Type Reset Description
15 SCIFFFE R 0h
SCIFFFE. SCI FIFO Framing error flag bit (applicable only if the
FIFO is enabled)
Reset type: SYSRSn
0h (R/W) = No frame error occurred while receiving the character,
in bits 7-0. This bit is associated with the character on the top of
the FIFO.
1h (R/W) = A frame error occurred while receiving the character in
bits 7-0. This bit is associated with the character on the top of the
FIFO.
14 SCIFFPE R 0h
SCIFFPE. SCI FIFO parity error flag bit (applicable only if the FIFO
is enabled)
Reset type: SYSRSn
0h (R/W) = No parity error occurred while receiving the character,
in bits 7-0. This bit is associated with the character on the top of
the FIFO.
1h (R/W) = A parity error occurred while receiving the character in
bits 7-0. This bit is associated with the character on the top of the
FIFO.
