of "USB Power Delivery Specification Revision 3.0, Version 1.2" provides the
|
|
different power levels and "6.4.1.3.1.6 Fast Role Swap USB Type-C Current"
|
|
provides a detailed description of the field. The sink PDO from current source
|
|
reflects the current source's(i.e. transmitter of the FRS signal) power
|
|
requirement during fr swap. The current sink (i.e. receiver of the FRS signal),
|
|
a.k.a new source, should check if it will be able to satisfy the current source's,
|
|
new sink's, requirement during frswap before enabling the frs signal reception.
|
|
This property refers to maximum current capability that the current sink can
|
|
satisfy. During FRS, VBUS voltage is at 5V, as the partners are in implicit
|
|
contract, hence, the power level is only a function of the current capability.
|
|
"1" refers to default USB power level as described by "Table 6-14 Fixed Supply PDO - Sink".
|
|
"2" refers to 1.5A@5V.
|

"3" refers to 3.0A@5V.
