8.7 Power-on reset and CE input
A missing clock, insufficient digital or analog V
initiate the reset sequence; all outputs are forced to 3-state (see
It is possible to force a reset by pulling the Chip Enable (CE) input to ground. After the
rising edge of CE and sufficient power supply voltage, the outputs LLC and SDA return
from 3-state to active, while RTS0, RTS1 and RTCO remain in 3-state and have to be
activated via I
