Manufacturer:SIPEX Description: The Processor Enable bit (bit 6) places every output channel on every output stream in Processor Mode; i.e., the contents of the Connection Memory LOW (CML, see Table 5) are output on the output streams once every frame unless the ODE input pin is LOW. If PE bit is HIGH, then the IDT72V8985 behaves as if bits 2 (Channel Source) and 0 (Output Enable) of every Connection Memory High (CMH, see Table 4) locations were set to HIGH, regardless of the actual value. If PE is LOW, then bit 2 and 0 of each Connection Memory High location operates normally. In this case, if bit 2 of the CMH is HIGH, the associated TX output channel is in Processor Mode. If bit 2 of the CMH is LOW, then the contents of the CML define the source information (stream and channel) of the time slot that is to be switched to an output. If the ODE input pin is LOW, then all the serial outputs are high-impedance. If ODE is HIGH, then bit 0 (Output Enable) of the CMH location enables (if HIGH) or disables (if LOW) for that particular channel. The contents of bit 1 (CCO) of each Connection Memory High Location (see Table 4) is output on CCO pin once every frame. The CCO pin is a 2.048 Mb/ s output, which carries 256 bits. If CCO bit is set HIGH, the corresponding bit on CCO output is transmitted HIGH. If CCO is LOW, the corresponding bit on the CCO output is transmitted LOW. The contents of the 256 CCO bits of the CMH are transmitted sequentially on to the CCO output pin and are synchronous to the TX streams. To allow for delay in any external control circuitry the contents of the CCO bit is output one channel before the corresponding channel on the TX streams. For example, the contents of CCO bit in position 0 (corresponding to TX0, CH0), is transmitted synchronously with the TX channel 31, bit 7. Bit 1's of CMH for channel 1 of streams 0-7 are output synchronously with TX channel 0 bits 7-0. |
