8.4 ID detector
In either the active or suspended power mode, the ID detector senses the condition of
the ID line and differentiates between the following three conditions:
Pin ID is floating; bit ID_FLOAT = 1
Pin ID is shorted to ground; bit ID_GND = 1
Pin ID is connected to ground through resistor R
ACC_ID
; bit ID_FLOAT = 0 and bit
ID_GND = 0.
The ID detector also has a switch that can be used to ground pin ID. This switch is
controlled by bit ID_PULLDOWN in the serial controller.
8.5 Pull-up and pull-down resistors
The pull-up and pull-down resistors include the following switchable resistors:
Pin DP pull-up
Pin DP pull-down
Pin DM pull-up
Pin DM pull-down.
The pull-up resistor is a context variable as described in the ECN_27%_Resistor
document. The variable pull-up resistor hardware is implemented to meet the USB
ECN_27% specification.
8.6 USB transceiver (ATX)
The behavior of the USB transceiver depends on the operation mode of the ISP1301:
In the USB mode, the USB transceiver block performs USB full-speed or
low-speed transceiver functions. This includes differential driver, differential
receiver and single-ended receivers.
In the transparent general purpose buffer mode or the UART mode, the USB
transceiver block functions as a level shifter between the pins DAT/VP and SE0/VM
and the pins DP and DM.
8.7 3.3 V DC-DC regulator
The built-in 3.3 V DC-DC regulator conditions the supply voltage (V
BAT
) for use in the
ISP1301:
V
BAT
= 3.6 V to 4.5 V: the regulator will output 3.3 V
±
10 %
V
BAT
< 3.6 V: the regulator will be bypassed.
The output of the regulator can be monitored on the V
REG(3V3)
pin.
8.8 Car kit interrupt detector
The car kit interrupt detector is a comparator that detects when the DP line is below
the car kit interrupt threshold V
PH_CR_INT
(0.4 V to 0.6 V). The car kit interrupt
detector is enabled in the audio mode only (bit AUDIO_EN = 1).
