Connection Memory Description
The MT90871 incorporates two connection memories, Local Connection Memory and Backplane Connection
Memory.
6.1
Local Connection Memory
The Local Connection Memory (LCM) is 16-bit wide with 4,096 memory locations to support the Local output
port. The most significant bit of each word, bit [15], selects the source stream from either the Backplane or the
Local port and determines the Backplane-to-Local or Local-to-Local data routing. Bits [14:13] select the control
modes of the Local output streams, namely the per-channel message and the per-channel high impedance
output control modes. In Connection Mode (Bit14 = LOW), Bits [12:0] select the source stream and channel
number as detailed in
Table 4
. In Message Mode (Bit14 = HIGH), Bits [12:8] are unused and Bits [7:0] contain
the message byte to be transmitted.
