FUNCTIONAL DEVICE OPERATION
OPERATION AFTER IDENTIFICATION
shows the case that an interrupt bit is already set due to
attachment of an accessory and WAIT = 0 when the first
delay time expires. In this case, INTB outputs high voltage in
the first delay time and then outputs low voltage after the first

delay time expires. The signal switches are not turned on until
the WAIT bit is written to ‘1’ by I 2 C. When the baseband reads
the interrupt registers via the I 2 C, the interrupt bits are
cleared and the INTB output returns to high.

TIMING OF THE SWITCHING ACTION (WAIT BIT)
If the INT_MASK bit is already set to ‘0’ before an
accessory is attached, the INTB outputs low voltage once an
interrupt bit is set and the following timing of the switching
action is controlled by the WAIT bit in the Control register. If
the WAIT bit is ‘1’ when the Attach interrupt bit is set and
before turning on the switches. The WAIT time is
programmed by the Switching Wait bits in the Timing Set 2
register. If the WAIT bit is ‘0’ when the Attach interrupt is
generated, the 34827 will not turn on the switches until the
WAIT bit is set to ‘1’ by I 2 C. Both cases are shown in the
INTB outputs low voltage, the 34827 waits for a WAIT time
