xxx allows to address physically a slave node. Therefore, these dynamic Ids cannot be used for more than eight stepper motors.
Only ten ROM pointers are needed for the AMIS-30623.
16.8 LIN Lost Behavior
16.8.1. Introduction
When the LIN communication is broken for a duration of 25000 consecutive frames ( = 1,30 s @ 19200 kbit/s) AMIS-30623 sets an
internal flag called “LIN lost”. The functional behavior depends on the state of OTP bits <SleepEn> and <FailSafe>, and if this loss in
LIN communication occurred at (or before) power on reset or in normal powered operation.
16.8.2. Sleep Enable
The OTP bit <SleepEn> enables or disables the entering in low-power sleep mode in case of LIN time-out. Default the entering of the
sleep-mode is disabled.
