DDC2B Protocol
DDC2B is constructed base on Philips I
2
C inter-
face. However, in the level of DDC2B, PC host is
fixed as the master and the monitor is always re-
garded asthe slave.Both master and slave can be
operated as a transmitter or receiver, but themas-
ter device determines which mode is activated. In
this protocol, address pointer is also used.
According to DDC2B specification, A0(for write
mode) and A1(for read mode) are assigned as the
default address of monitors.
The reception of the incoming data in write mode
or the updating of the outgoingdata in read mode
should be finished within the specified time limit. If
software in the slave’s side cannot react to the
master in time, based on I
2
C protocol,SCL pin can
be stretched low to inhibit the further action from
the master. The transaction can be proceeded in
either byte or burst format.
