There are two modes of demultiplexing that can be set for the 16 channels of

the external analyzer: mixed clocks and true demultiplexing.

Choose "off" to turn slave clocks OFF. If the slave clock is "off", all 16

external bits are clocked with the emulation clock.

Choose "mixed" to specify the mixed clock demultiplexing mode. In this

mode, the lower eight external bits (0-7) are latched when the slave clock (as

specified by your answers to the next four questions) is received. The upper

eight bits and the latched lower eight are then clocked into the analyzer

when the emulation clock is received (see the figure below).

If no slave clock has appeared since the last master clock, the data on the

lower 8 bits of the pod will be latched at the same time as the upper 8 bits. If
