LIN Reception Manipulation Outline
Notes: 1.
The wakeup signal is sent by the pin edge detector, UARTC is enabled, and the SBF
reception mode is set.
2.
The receive operation is performed until detection of the stop bit. Upon detection of SBF
reception of 11 or more bits, normal SBF reception end is judged, and an interrupt signal is
output. Upon detection of SBF reception of less than 11 bits, a SBF reception error is
judged, no interrupt signal is output, and the mode returns to the SBF reception mode.
3.
If SBF reception ends normally, an interrupt signal is output. The timer is enabled by a SBF
reception complete interrupt. Moreover, error detection for the UCnOVE, UCnPE, and
UCnFE bits of the UCnSTR register is suppressed and UART communication error
detection processing and UARTCn receive shift register and data transfer of the UCnRX
register are not performed. The UARTCn receive shift register holds the initial value, FFH.
4.
The RXDCn pin is connected to TI (capture input) of the timer, the transfer rate is
calculated, and the baud rate error is calculated. The value of the UCnCTL2 register
obtained by compensating the baud rate error after dropping UARTC enable is set again,
causing the status to become the reception status.
5.
Check-sum field distinctions are made by software. The UARTC is initialized following CSF
reception, and the processing for setting the SBF reception mode again is performed by
software.
