Claim 6:
7. The system as claimed in claim 6, comprising a configuration, wherein a handshaking mechanism is enabled between the IC and a tester during the ATPG mode, wherein the IC applies a weak pull up on a CC line at the end of each shift-out phase after completion of Biphase Mark Coding (BMC) encoded data transfer and tester sends an acknowledgment to the IC by pulling the CC line low using a strong pulldown for transitioning scan phase from shift-out to shift-in and direction change of the CC pin from TX to RX, wherein the tester applies weak pullup on the CC line at the end of each shift-in phase and each capture phase after completion of the BMC encoded data transfer and IC sends acknowledgement to the tester by pulling the CC low using a strong pull down for transitioning scan phase from shift-in to capture or shift-out as well as from capture to shiftout and direction change of CC pin from receiver (RX) to transmitter (TX) while transitioning to shift-out phase.
