... Freescale Semiconductor, Inc. match bit as defined by the mask register is ignored for this operation. The operation of the MCM69C432 guarantees that no more than one matching entry can exist in the table, unless they were accidently loaded using fast–entry mode. This must be avoided by the user, as the results of subse- quent matches and deletes will be undefined ...

... Freescale Semiconductor, Inc. SET FAST–READ REGISTER VALUE This operation defines the table address that is output by the fast–read operation. The least significant 14 bits of I/O register 0 are copied to the fast–read register. The queue must be empty when this instruction is executed. FAST READ This operation is used to output the contents of one entry in the CAM table. The fast– ...

... Freescale Semiconductor, Inc. INSTRUCTION SET A 5–pin IEEE Standard 1149.1 Test Port (JTAG) is in- cluded on this device. When the TAP (Test Access Port) con- troller is in the SHIFT–IR state, the instruction register is placed between TDI and TDO. In this state, the desired instruction would be serially loaded through the TDI input. TRST resets the TAP controller to the test– ...
