dp_pull-down
1
rd/s/c
bit 2
1 = Connect pull-down to D+
dm_pull-down
1
rd/s/c
bit 3
1 = Connect pull-down to D-
id_gnd_out
1
rd/s/c
bit 4
1 = Connect ID pin to ground
vbus_drv
1
rd/s/c
bit 5
1 = Power VBUS with charge pump
vbus_dischrg
1
rd/s/c
bit 6
1 = Discharge VBUS through a resistor
vbus_chrg
1
rd/s/c
bit 7
1 = Charge VBUS through a resistor
Control Register 3
Set & Clear
set - 12h
clr – 13h
1
set = 1
1
clr = 0
pwr_dn
1
rd/s/c
bit 0
1 = Power Down mode.
cp_off
1
rd/s/c
bit 1
1
=
turns
charge
pump
OFF.
(Charge pump generates 5V for powering VBUS)
id_det_off
1
rd/s/c
bit 2
0 = ID comparators ON.
1 = Turns ID comparators OFF.
Note: Powering down ID comparators does not shut
off ID pin pull-up.
cr_int_sel
1
rd/s/c
bit 3
Car Kit interrupt select:
0 = Detect < 0.5V level on D+
1 = Detect > 3.0V level on D+
sess_end_en
1
rd/s/c
bit 4
0 = no action.
1 = When bdis_acon_en = 0, switches Bit 6 of the
Interrupt Register to indicate Session End comparator
status.
ext_osc
1
rd/s/c
bit 5
0 = Internal oscillator drives charge pump
1 = External oscillator drives charge pump (Input
source = GPIO_2)
rcs_dis
1
rd/s/c
bit 6
0 = Activate current source. Weak pull-up on ID pin.
1 = Disable (bypass) current source pull-up on ID pin.
Strong pull-up on ID pin.
scl_en
1
rd/s/c
bit 7
0 = I
2C clock line only transmits.
1 = Bi-directional I
2C clock line.
Bi-directional clock is required if target device is to be
able to control data rate by holding SCL low.
