2.1.3
BI-DIRECTIONAL MODE
The DDC Monitor Port can be switched into the bi-
directional Mode (Figure 2-3) by applying a valid high to
low transition on the Bi-directional Mode Clock (DSCL).
When the device has been switched into the Bi-direc-
tional Mode, the VCLK input is disregarded, with the
exception that a logic high level is required to enable
write capability. This mode supports a 2-wire bi-direc-
tional data transmission protocol. In this protocol, a
device that sends data on the bus is defined to be the
transmitter, and a device that receives data from the
bus is defined to be the receiver. The bus must be con-
trolled by a master device that generates the Bi-direc-
tional Mode Clock (DSCL), controls access to the bus
and generates the START and STOP conditions, while
the DDC Monitor Port acts as the slave. Both master
and slave can operate as transmitter or receiver, but the
master device determines which mode is activated.
2.2
Microcontroller Access Port
The Microcontroller Access Port supports a bi-direc-
tional 2-wire bus and data transmission protocol. A
device that sends data onto the bus is defined as trans-
mitter, and a device receiving data as receiver. The bus
has to be controlled by a master device which gener-
ates the serial clock (MSCL), controls the bus access,
and generates the START and STOP conditions, while
the Microcontroller Access Port works as slave. Both
master and slave can operate as transmitter or receiver,
but the master device determines which mode is acti-
vated.
