NEWFRM—Status bit denoting the start of a new frame. Reading the LIN-UART Receive
Data register resets this bit to 0.
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 (though it may be 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 while the data is sampled (center of bit time). If this bit is set, it does not indicate that
the receive data is corrupt (though it may be 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 may be read following a
break (LIN WAKE-UP or BREAK) so software can determine 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.
00_xxx LIN UART hardware rev
01_xxx reserved
10_xxx reserved
11_xxx reserved
LIN-UART Control 0 Register
The LIN-UART Control 0 Register, shown in Table 71, configures the basic properties of
the LIN-UART’s transmit and receive operations. A more detailed discussion of each bit
follows the table.
