The hardware sequencer and buffers module is part of the SIMCOP subsystem in the ISS.
Figure 9-178 shows the integration of the hardware sequencer and buffers in the SIMCOP subsystem.
Figure 9-178 Hardware Sequencer and Buffer IntegrationTable 9-2608 lists the integration attributes, Table 9-2609 lists the clocks and resets, and Table 9-2610 lists the hardware requests.
| Module Instance | Attributes | |
