Table 15.11 Receive Errors and Conditions for Occurrence

Receive Error

Abbreviation

Occurrence Condition

Data Transfer

Overrun error

ORER

When the next data reception is

completed while the RDRF flag

in SSR is set to 1

Receive data is not

transferred from RSR to

RDR

Framing error

FER

When the stop bit is 0

Receive data is transferred

from RSR to RDR

Parity error

PER

When the received data differs

from the parity (even or odd) set

in SMR

Receive data is transferred

from RSR to RDR

Figure 15.8 shows an example of the operation for reception in asynchronous mode.
