AMIS−30623
Note: The Secure Position is coded on 11 bits only,
providing actually the most significant bits of the position, the
non coded least significant bits being set to ‘0’. The Secure
Position in OTP has only 9 bits. The two least significant bits
are loaded as ‘0’ to RAM when copied from OTP.

(*) restriction on speed
SleepEn IF <SleepEn> = 1 −> AMIS−30623
always goes to low−power sleep mode incase of
LIN timeout.
IF <SleepEn> = 0, there is no more
automatic transition to low−current sleep mode
(i.e. stay in stop mode with applied hold
current, unless there are failures). Exception to
this rule are the states <Standby> and
<Shutdown>, in which the device can enter
sleep regardless of the state of SleepEn.
Note: The <SleepEn> function acts for the LIN command
“SLEEP” too. When <SleepEn> = 1 and the Sleep command
is received the 30623 will go into Sleep. In case the
<SleepEn> = 0 the 30623 will go into stop mode.
