5 This parameter will not be tested but guaranteed by design

6 This time is necessary between two write accesses to control e.g. channel 1 to 8 during the first access and

channel 9 to 16 during the second access. To get the correct diagnostic information, the transfer delay time has

to be extended to the maximum fault delay time td(fault)max = 200µs.
