CC CONTROL REGISTER (CC_CTL)

The register controls the pull-down resistors and current sources on the respective CC1/CC2 pin.

Address:

0820h

Size:

16 bits

Description

Type

Default

RA Detect

When set, indicates that an RA resistor has been detected.

This bit is set by the device when Standalone Operation is configured for

standalone mode. The device updates this field after an attach has been

detected.

CC Comparator Control

00b: CC Comparator and DAC powered-down

01b: CC Comparator samples CC1

10b: CC Comparator samples CC2

11b: CC Comparator samples CC1 and CC2

Note:

A sample is taken every 100 us. The current source reference shall

also be powered down when a value of 00b is set.

Note:

This field is RO and the contents are 11b when standalone mode

is enabled.

Note:

This field is used in conjunction with the CCx Sample Enable Reg-

isters (CCx_SAMP_EN) which constrains the number of thresh-

olds monitored on the enabled CC pin(s).

Note 9-7

00b

CC Communication Select

0b: CC1 is used for baseband communication.

1b: CC2 is used for baseband communication.

This bit is set by the device when Standalone Operation is configured for

standalone mode. The device updates this field after an attach has been

detected.

This bit is RO and reflects the state determined by the internal logic. In stand-

alone mode, this bit matches the state of the ORIENTATION pin (UPD360-A/

UPD360-B only).

CC2 RP Value

00b: RP current source disabled

01b: RP current source enabled, default USB power

10b: RP current source enabled, 1.5A

11b: RP current source enabled, 3.0A

Controls RP value on CC2 pin.

CC1 RP Value

00b: RP current source disabled

01b: RP current source enabled, default USB power

10b: RP current source enabled, 1.5A

11b: RP current source enabled, 3.0A

Controls RP value on CC1 pin.
