There are multiple configuration parameters that configure or modify the functionality of the Low Power Distributor Q-Channel.
The following table shows the LPD-Q configuration parameters.
Table 2-1 LPD-Q configuration parameters
0 = The LPD-Q operates as an expander.
1 = The LPD-Q operates as a sequencer.
|NUM_QCHL||2-32||2||Sets the number of device (dev_*) Q-Channel interfaces in the LPD-Q.|
0 = A synchronizer is not present on the ctrl_qreqn_i input.
1 = A synchronizer is present on the ctrl_qreqn_i input.
0 = Synchronizers are not present on the dev_qacceptn_i[N] or dev_qdeny_i[N] inputs.
1 = Synchronizers are present on the dev_qacceptn_i[N] and dev_qdeny_i[N] inputs.
0 = Support for denying a quiescence request by using dev_qactive_i[N] is not included.
1 = Support for denying a quiescence request using dev_qactive_i[N] is included. Synchronizers are included on the dev_qactive_i[N] inputs, where these signals are used internally.
Note:The path from a device to the controller QACTIVE is combinatorial, irrespective of whether synchronizers are present.
