E.2.1
The CX28500 (HDLC Controller) device operates as the Slave on the Time-Slot bus, and the other device (usually
CX29503) is the Master. The Master generates TSBUS clocks and control signals and the CX28500 device
responds by transmitting data to or receiving data from the Master device. The Master generates a TSBUS Frame
Strobe (TSB_STB) on the rising edge of TSB_CLK. The Time Slot Bus frame strobe TSB_STB indicates the start
of an N time slot Frame carrying payload data, where the standard value of N is 84 (but this is configurable).

Framers with the same Set Number must be configured for the same data signal (i.e., all framers within a set must be
configured for DS1 or E1 signals but not both).
