termination 9 and from there back via line 8 to low side driver 3 besides these two binary states the flexray r specification is also known to comprise what is known as an u201c idle u201d state which is obtained when the signal edges change between the binary states fig2 a shows the driver node as function block 12 chip or module generally with four bus connection terminals 13 16 image section b shows the interconnection of the terminals 13 16 of the function block 12 when used as a flexray r driver image section c shows the interconnection of the terminals 13 16 of the function block 12 when used as a can driver with two can drivers advantageously being able to be implemented for bus u201c can1 u201d and u201c can2 u201d the aforementioned drivers are respectively compiled from two individual high side driver stages 1 2 and two low side driver stages 3 4 for which the connections 13 16 of all four stages are routed out individually external interconnection now makes it possible to present either a flexray driver by shorting pins 13 and 16 and pins 14 and 15 with the bus termination being situated between lines 8 and 9 or two can drivers by interconnecting the termination for bus u201c can1 u201d between pins 14 and 15 and a termination for bus u201c can2 u201d between pins 13 and 16 as an alternative to the option of stipulating the mode of operation by means of external interconnection there is likewise preferably the option of automatically associating the external connections 13.
