Frame Slot Mode

Synch
This mode is useful only for Master nodes. It respects the following rule: each frame slot shall be
longer than or equal to TFrame_Maximum.
If the Frame Slot Mode is enabled (FSDIS = 0) and a frame transfer has been completed, the
TXRDY flag is set again only after TFrame_Maximum delay, from the start of frame. So the Mas-
ter node cannot send a new header if the frame slot duration of the previous frame is inferior to
TFrame_Maximum.
If the Frame Slot Mode is disabled (FSDIS = 1) and a frame transfer has been completed, the
TXRDY flag is set again immediately.
The TFrame_Maximum is calculated as below:
If the Checksum is sent (CHKDIS = 0):
If the Checksum is not sent (CHKDIS = 1):
Note:
• THeader_Nominal = 34 x TBit
• TResponse_Nominal = 10 x (NData + 1) x TBit
• TFrame_Maximum = 1.4 x (THeader_Nominal + TResponse_Nominal + 1)
• TFrame_Maximum = 1.4 x (34 + 10 x (DLC + 1 + 1) + 1) x TBIT
• TFrame_Maximum = (77 + 14 x DLC) x TBIT
• THeader_Nominal = 34 x TBit
• TResponse_Nominal = 10 x NData x TBit
• TFrame_Maximum = 1.4 x (THeader_Nominal + TResponse_Nominal + 1
• TFrame_Maximum = 1.4 x (34 + 10 x (DLC + 1) + 1) x TBIT
• TFrame_Maximum = (63 + 14 x DLC) x TBIT
Data 1
The term “+1” leads to an integer result for TFrame_Max (LIN Specification 1.3)
