Bits 7 and 6: Interleave Bus Operation Mode Select 1 and 0 (IBOMS[1:0]). These bits determine the
configuration of the IBO (interleaved bus) multiplexer and inform the framers of the IBO configuration. These bits
should be used in conjunction with the Rx and Tx IBO control registers within each of the framer units. These bits
control Channels 1 to 4. Additional information concerning the IBO multiplexer is given in Section 9.8.2. These bits
must be set whether using the internal IBO mux or externally ganging the pins.
**The DS26514 is limited to slots 1-4 in this mode. The DS26514 cannot be assigned to slots 5-8.
Bits 5 and 4: Backplane Clock Select 1 and 0 (BPCLK[1:0]). These bits determine the clock frequency output on
the BPCLK1 pin.
Bit 2: Receive Frame/Multiframe Sync Select (RFMSS). This bit controls the function of all four
RMSYNCn/RFSYNCn pins.
Bit 1: Transmit Channel Block/Clock Select (TCBCS). This bit controls the function of all four
TCHBLKn/TCHCLKn pins.
Bit 0: Receive Channel Block/Clock Select (RCBCS). This bit controls the function of all four
RCHBLKn/RCHCLKn pins.
