UPD360

Note 9-7

This bit is RO when operating in standalone mode. Otherwise it is R/W.

Note 9-8

This field’s default is a function of the PWR_CAP0 and PWR_CAP1 pins when in standalone DFP

mode (see Section 9.8.1, "Configuration Selection") (UPD360-A/UPD360-B only). Otherwise the

default is 00b.

Note 9-9

For standalone DFP and standalone UFP, the value is 00b until the system reset completes.

Afterwards, the default for standalone DFP is 11b and for standalone UFP is 01b.

9.12.21

CC THRESHOLD X REGISTERS (CC_THRX)

Note 9-10

The default varies as shown in Table 9-12.

DFP Current Advertisement

When Standalone Operation is configured for standalone mode and the

device is configured as UFP, Device Role, this field indicates the DFP’s adver-

tised current. Otherwise this field shall be read back 00b.

The device updates this field after an attach has been detected.
