cmd8 = control command
EXPLANATION
With this command you may change the device address, the value of t_ignore, which
is the time between a master frame and a slave frame before RTI (Reply Timeout
Interrupt) occurs, or you may execute a control command.
Possible values for t_ignore are the following:
— 15 (hex), which corresponds to 21.3 us
— 2A (hex), which corresponds to 42.7 us
— 40 (hex), which corresponds to 64.0 us
— 55 (hex), which corresponds to 85.4 us
The available control commands are the following:
— 01 (hex)AON: Enable Bus Administrator
— 02 (hex)AOF: Disable Bus Administrator
— 04 (hex)SPL: Switch to next Periodic List
— 08 (hex)TMS: Transfer mastership
— 10 (hex)SLA: Trust always Line_A
— 20 (hex)SLB: Trust always Line_B
— 40 (hex)CLA: Clear Line_A error counter
— 80 (hex)CLB: Clear Line_B error counter
For more information, refer to the TCN Standard (IEC 61375-1). The above
command name abbreviations are from the Standard.
