An undervoltage and initialization circuit holds the parts in a disconnected state which
presents high-impedance to all SDAn and SCLn pins during power-up. A LOW on the
ENABLE pin also forces the parts into the low current disconnected state when the I
essentially zero. As the power supply is brought up and the ENABLE is HIGH or the part is
powered and the ENABLE is taken from LOW to HIGH it enters an initialization state
where the internal references are stabilized and the 92 A input pull-ups (on the
PCA9513A) is enabled. At the end of the initialization state the ‘Stop Bit And Bus Idle’
detect circuit is enabled. With the ENABLE pin HIGH long enough to complete the
initialization state (t

mode. It also disables the rise time accelerators, isolates SDAIN from
SDAOUT and isolates SCLIN from SCLOUT.
