The last field of a frame is the checksum.
In LIN 2.1, the checksum contains the inverted eight bit sum with carry over all data bytes and
the protected identifier. This calculation is called enhanced checksum.
In LIN 1.3, the checksum contains the inverted eight bit sum with carry over all data bytes.
This calculation is called classic checksum.
Frame identifiers 60 (0x3C) to 61 (0x3D) shall always use classic checksum.
As shown in
combined to drive two interrupts. Each of these flags have their respective enable interrupt bit
in LINENIR register.
