The IC determines the
amplitude of the first
negative pulse of the
ASI telegram. This
amplitude is asserted
to be VSIG / 2.
"DC level"
Parameter
Falling edge of the internal 5V supply voltage that activates the
internal power-on-reset signal
Rising edge of the internal voltage 5V supply voltage that causes
the deactivation of the internal power-on-reset signal what will
cause the start of the INIT procedure
Chip temperature that causes an overtemp shut down
Receiver comparator threshold level (refer to Figure 3-3)
Reset time - either after the end bit of the sent out slave response
that is related to a received master Call Reset AS-i-Slave - or after
the IC has deactivated its power-on-reset signal
