Patent ID: 7219250

Claim:
A method for detecting status indications, comprising the steps of: a1) raw status indications are read into an input storage stage of a first reference clock domain such that the read status indications are available in said input storage stage synchronized to a first reference clock of said first reference clock domain; a2) said read status indications are input into an output storage stage of a second reference clock domain, such that the status indications are available in said output storage stage synchronized to a second reference clock of said second reference clock domain, said second reference clock of said second reference clock domain having a different phase and/or frequency to said first reference clock; b) said status indications in said input storage stage are shifted to an intermediate storage stage of said first reference clock domain synchronized to said first reference clock; and c) in response to a read request signal being input into said output storage stage: c1) a hold signal is applied to said intermediate storage stage for holding a current status indication in said intermediate storage stage and blocking a shifting of a new status indication from said input to said intermediate storage stage; and c2) during said hold signal a read out signal is applied to said output storage stage for reading the current status indication in said intermediate storage stage into said output storage stage synchronized to said second reference clock.
