■ When a reception error is generated
• Transfer in UART mode with 8-bit data length, parity on, and 1 stop bit
Fig. 13-2-13 Timing Chart (10)
When "reception end" is set as the reception interrupt source, an interrupt request is generated when reception ends,
regardless of whether or not an error occurred.
When "reception end with error" is set as the reception interrupt source, an interrupt request is generated when
reception ends with an error having occurred. (An interrupt request is not generated at the moment that the error
occurred.)
An overrun error is generated when reception of the next data is completed before previously received data is read
from the SC0RXB. In this event, the previously received data is lost. The overrun error indicator flag (SC0OEF)
is updated at the moment the final data bit is received.
A parity error is generated when 0-fixed parity is set and a "1" is received, when 1-fixed parity is set and a "0" is
received, when even parity is set and an odd number of ones is received, or when odd parity is set and an even
number of ones is received. The parity error indicator flag (SC0PEF) is updated at the moment the parity bit are
received.
A framing error is generated when "0" was received for the stop bit. The framing error indicator flag (SC0FEF) is
updated at the moment the stop bit is received.
