0 = The current byte is not the first data byte of a new frame.
1 = The current byte is the first data byte of a new frame.
MPRX—Multiprocessor Receive
Returns the value of the last multiprocessor bit received. Reading from the LIN-UART
receive data register Resets this bit to 0.
Digital Noise Filter Mode Status Field (MSEL = 001B)
NE—Noise Event
This bit is asserted if digital noise is detected on the receive data line while the data is
sampled (center of bit time). If this bit is set, it does not mean that the receive data is
corrupted (in extreme cases), just that one or more of the noise filter data samples near the
center of the bit time did not match the average data value.
LIN Mode Status Field (MSEL = 010B)
NE—Noise event
This bit is asserted if some noise level is detected on the receive data line when the data is
sampled (center of bit time). If this bit is set, it does not indicate that the receive data is
corrupt (in extreme cases), just that one or more of the 16x data samples near the center of
the bit time did not match the average data value.
RxBreakLength—LIN mode received break length. This field is read following a break
(LIN WAKE-UP or BREAK) so software determines the measured duration of the break. If
the break exceeds 15 bit times the value saturates at
.
1111B
Hardware Revision Mode Status Field (MSEL = 111B)
This field indicates the hardware revision of the LIN-UART block.
