Port LP <strong>Data</strong> Bit 1<br />

The LIN Physical Layer LPTXD input (see Figure 15-1) can be directly controlled by this register bit. The routing<br />

of the LPTXD input is done in PIM Module, see PIM Block guide for more info.<br />

Port LP <strong>Data</strong> Bit 0<br />

Read-only bit. The LIN Physical Layer LPRXD output state can be read at any time.<br />
