Bit 4: Framing error (FER)

Bit 4 indicates that a framing error has occurred during reception in asynchronous mode.

Bit 4

FER

Description

Reception in progress or completed*

(initial value)

Clearing condition:

After reading FER = 1, cleared by writing 0 to FER

A framing error has occurred during reception

Setting condition:

When the stop bit at the end of the receive data is checked for a value of 1 at the end

of reception, and the stop bit is 0*

Notes: 1. When bit RE in SCR3 is cleared to 0, bit FER is not affected and retains its previous

state.

2. Note that, in 2-stop-bit mode, only the first stop bit is checked for a value of 1, and the

second stop bit is not checked. When a framing error occurs the receive data is

transferred to RDR but bit RDRF is not set. Reception cannot be continued with bit FER

set to 1. In synchronous mode, neither transmission nor reception is possible when bit

FER is set to 1.
