Minimal separation time between frames in ms.

The timer starts when the frame is queued and the next frame is

STmin is chosen by the receiver and transmitted in the FC

(Flow Control) frame. See also: ISO 15765-2:2016

Number of CF (Contiguous Frame) PDUs before next FC (Flow Control)

frame is sent. Zero value means all frames are sent consecutive

A BS counter at the sender counts from one to BS. When BS is reached,

the sender waits for a FC frame again an BS is reset.
