CHAPTER 20 LIN-UART
20.4.5 Extended Status/Control Register (ESCR)
This register provides several LIN functions, direct access to the SINn and SOTn pins
and setting of continuous clock output and sampling clock edge in LIN-UART
synchronous clock mode.
■ Extended Status/control Register (ESCR)
Figure 20.4-6 shows the Configuration of the extended status/control register (ESCR), and Table 20.4-4
shows the function of each bit.
