LOGIC AND STATE MACHINE
Internal state machine executes the detection and
identification flow and turns on or off the signal switches
according to the identification result.
I 2 C INTERFACE
I 2 C interface circuit is an I 2 C slave device. It receives
commands and data from an I 2 C master device and transfers
them to internal registers of 34827. It also transfers the data
from the registers of 34827 to the I 2 C master device.
TEST INTERFACE
Test interface connects to a test block of the baseband.
SWITCH ARRAY
Switch array consist of switches for UART, USB and audio
signal channels.
INTERNAL POWER SUPPLY
This block outputs power supply for the internal digital IO
interface and also outputs high power supply for all internal
blocks and for the external battery charger. The input power
supplies of the block include VBUS, VDD and VDDIO.
VBUS DETECT
This block detects whether the power supply at VBUS pin
is present.
ID ADC
An internal 5-bit ADC measures the resistance at the ID
pin. The result is sent to the Logic and State Machine block
to determine what accessory is attached.
ID DETECT
This block generates current sources and other signals to
the ID pin to help the ID ADC block measure the ID
resistance.
