Table 68. LIN-UART Status 0 Register - standard UART mode (U0STAT0)
RXD—Receive Data
LIN-UART receiver data byte from the RXD pin
The LIN-UART Status 0 Register identifies the current LIN-UART operating configura-
tion and status. Table 68 describes the Status 0 Register for standard UART mode.
69, which follows on page 132, describes the Status0 Register for LIN mode. A more
detailed discussion of each bit follows each table.
