MCU completes to receive the data 1, and turns the reception done flag on.
An error occurs while MCU is receiving the data 2,
MCU detects the reception error and turns the reception error flag on.
CPU loads the MCU reception done flag and MCU reception error flag which were turned on at
and by the I/O refresh,
CPU turns X0(X2) and XA(XC) on.
MCU receives the data 3.
An error occurs while MCU is receiving the data 4.
MCU receives the data 5.
An error occurs while MCU is receiving the data 6.
MCU receives the data 7.
An error occurs while MCU is receiving the data 8.
CPU receives the first buffer.
As no error is detected during the reception of the first buffer, the reception error flag remains OFF.
CPU receives the second buffer.
As an error was detected during the reception of the second buffer, the reception error flag turns on.
On state is effective until the next scan.
CPU receives the third buffer.
As no error is detected during the reception of the third buffer, the reception error flag remains OFF.
CPU receives the forth buffer.
As an error was detected during the reception of the forth buffer, the reception error flag turns on.
On state is effective until the next scan.
