4.5. CNTL Bus (CNTL[13:0])

The CNTL bus (CNTL[13:0]) defines the operation. The function of the CNTL bus is classified into

four categories as follows:

• The control of a search operation

• The control of a weighted search operation

• The control of a command

• The control of an access to a register

As shown below, CNTL[13:12] defines the operation, and CNTL[11:5] defines the parameters, and

CNTL[4:0] defines the Mask Register number. As for the parameters and the Mask Register number,

refer to the datasheet.
