The DE to Start bit setup time is calculated as follows:
The special modes of the LIN-UART:
•
•
The LIN-UART has a common control register (Control 0), which has a unique register
address and several mode specific control registers (multiprocessor control, noise filter
control, and LIN control) which share a common register address (Control 1). When the
Control 1 address is read or written, the mode select (
and status register determines which physical register is accessed. Similarly, there are mode
specific status registers, one of which is returned when the Status 0 register is read,
depending on the MSEL field.
The LIN-UART features a MULTIPROCESSOR (9-bit) mode which uses an extra (9
for selective communication when a number of processors share a common UART bus. In
MULTIPROCESSOR mode (also referred to as 9-Bit mode), the multiprocessor bit (
transmitted immediately following the 8 bits of data and immediately preceding the
bit(s) as illustrated in
