14.2.12 FIFO Error Register (SCFER)
The FIFO error register (SCFER) indicates the data location at which a parity error or framing
error occurred in receive data stored in the receive FIFO data register (SCFRDR).
SCFER can be read at all times.

Bits 15 to 0—Error Data Flags (ED15 to ED0): These flags indicate the data location in the
receive FIFO data register at which an error occurred. When data in the nth stage of the buffer
contains an error, the nth bit is set to 1. Note that this register is not cleared by setting the RFRST
bit to 1 in SCFCR. To clear this register, read all the receive data in which the error occurred from
the SCFRDR register before setting the RFRST bit to 1 in SCFCR to clear SCFRDR.
Bits 15 to 0:
ED15 to ED0
Description
0
No parity or framing error in data in corresponding stage of register FIFO
(Initial value)
1
Parity or framing error present in data in corresponding stage of register FIFO
Note: A reset operation is performed in the event of a reset, when the module standby function is
initiated, or in standby mode. Also, these flags are cleared by reading the data in which the
parity error or framing error occurred from SCFRDR.
