Note:
The relationship between the J1 and the SPE signals is shown for illustration purposes only.
For the STS-3 format, there will be three J1 pulses, which indicate the start of each of the
STS-1 SPEs. The STS-1 SPE added to the bus is shown for STS-1 number 1. STS-1 number
2 will occur one clock cycle later. STS-1 number 3 will occur two clock cycles later. There is
always a one byte delay between the AC1J1/ASPE input signals and the AD(7-0) output
leads.
