The USB-Serial bridge in the CCG1 Host board acts as a USB-I
2
C master bridge. The USB-Serial bridge is used to receive
USB vendor commands and translate them into a set of I
2
C-based commands. These I2C commands are addressed to the
CCG2 controller, which translates them into the required USB-PD messages. Standard DFP implementations can only
initiate USB-PD commands when a USB-PD power contract is in place. Since the DFP cannot setup a power contract
while
a
power
consumer
(Upstream
Facing
Port
or
UFP)
is
not
present,
programming
the
CCG2-based EMCA cable requires both a host (DFP) and client (UFP) to be connected, as illustrated in
