Figure 6 - Output Bit Advancement Timing

This programming feature is provided to assist in designs where per stream routing delays are significant and

different.

The OSBA bits in the Group Control Registers are used to set the bit-advancement for each of the corresponding

serial output stream groups. Figure 6 illustrates the effect of the OSBA settings on the output timing.

There are limitations when the ZL50073 is programmed to use CKi2 - 0 as the output stream clock source:

• If the selected reference clock frequency is 65 MHz or 32 MHz, the granularity of the advancement is

reduced to 1/2 the clock period

• If the selected reference clock frequency is 16 MHz or 8 MHz, bit advancement is not available and the

output streams are driven at the nominal times

6.0

Message Mode

In Message Mode (MSG), microprocessor data can be broadcast to the output data streams on a per-channel

basis. This feature is useful for transferring control and status information to external circuits or other TDM devices.

For a given output channel, when the corresponding Per Channel Function (bits 31 - 29) in the Connection Memory

are set to Message Mode (010), the Connection Memory’s lowest data byte (bits 7 - 0) is output in the timeslot.

Refer to Section 14.1.1, Connection Memory Bit Functions, for programming details.

To increase programming bandwidth, the ZL50073 has separate addressable 32 bit memory locations, called

Connection Memory Least Significant Bytes (LSB), which provide direct access to the Connection Memories’
