A Simple Keypad Using LIN with the MC68HC908QT/QY MCU
contain the LIN driver implementation code, which should not normally be
modified by the user.
The subfolder Prm contains the project parameter files (.prm), to define the
ROM/RAM memory locations of the MCU.
In folders Startup Code and Libs are the header/implementation files and the
necessary libraries — Start08.c, MC68HC908QY4.c, MC68HC908QY4.h and
ansi.lib.
The LIN message frames used in the application are defined in the file called
LINmsg.c. This is where specific IDs must be defined by the user for each
application message. This file also contains information that indicates whether
the message is designated for reception or for transmission.
The message ID is written in hexadecimal format with the parity bits included.
The data field can be 1 to 8 bytes long. For this application, two message IDs
are used, as shown in

For More Information On This Product,
The message ID equal to 0x1A (0x1A with the parity bits included) is
used for reception.
The message ID 0x1B (0x5B with the parity) is used for transmission.
