Figure 15.1. DDC1 Mode Timing Diagram
15.2. DDC2B + Slave & Master Mode Bus Interface
The built-in DDC2B+ I
2
C bus Interface features as follows
-
SLAVE mode (NT6862 is addressed by a master
which drives SCL signal)
-
MASTER mode (NT6862 addresses external device
and send out SCL clock)
-
Compatible with I
2
C bus standard
-
One default address (A0H) and one programable
address
-
Automatic wait state insertion
-
Interrupt generation for status control
-
Detection of START and STOP signals
The DDC2B+ will be activated as SLAVE mode initially.
Users can switch to MASTER mode by clearing the MODE
bit under either of these conditions listed as follows:
1. After entering to DDC1 function and clearing this bit, the
system will be changed from DDC1 to DDC2B+
MASTER mode operation.
2. After entering to DDC2B+ slave mode function and
clearing this bit, the system will changed from slave
mode into master mode operation.
As clearing MODE bit, system will send out a 'START'
condition and wait for user to put the calling address into
CH0/1TXDAT control register. Notice that user must
predetermine the direction of master mode transmission
before putting calling address.
Below is the DDC2B+ function with channel 0, and the
manipulation of channel 1 is the same as channel 0.
