Figure 6 - Local Port Timing Diagram for 2,4,8 and 16Mb/s stream rates
2.2.1.2
Local Output Port
The bit rate for each output stream is selected by writing to a dedicated Local Output Bit Rate Register
(LOBRR0-15). Refer to Table 40, Local Output Bit Rate Register (LOBRRn) Bits.
Operation of stream data in the Connection Mode or the Message Mode is determined by the state of the LMM
bit, and the channel High-impedance state is controlled by the LE bit of the Local Connection Memory. The
data source (i.e. from the Local or Backplane Data Memory) is determined by the LSRC bit of the Local
Connection Memory. Refer to Section 6.1 and Section 12.3.
2.2.2
Backplane Port Rate Selection
The Backplane port has 16 input (BSTi0-15) and 16 output (BSTo0-15) data streams. All input and output
streams may be individually selected for operation at a data rate of either 2.048Mb/s, 4.096Mb/s, 8.192Mb/s or
16.384Mb/s. The timing of the input and output clocks and frame pulses are shown in Figure 7, Backplane Port
Timing Diagram for 2, 4, 8, and 16Mb/s stream rates.
2.2.3
Backplane Input Port
The bit rate for each input stream is selected by writing to a dedicated Backplane Input Bit Rate Register
(BOBRR0-15). Refer to Table 42, Backplane Input Bit Rate Register (BIBRRn) Bits.
