Serial Scan Interface (SSI)
TCK CONTROL
TCK CONTROL is the central control block that enables or
disables shift operations and provides byte alignment for the
shifter/buffers. The state of all shifter/buffers and the 32-bit
counter (CNT32) is evaluated here and TCK is stopped and
started. A clock enable circuit allows the “TCK enable” signal
to change only when SCK is low; therefore, TCK always
stops low. TCK does not toggle (remains low) under the fol-
lowing conditions:
TDO Shifter/Buffer is enabled and empty.
TDO Shifter/Buffer is enabled in PRPG mode and is not
fully loaded.
TDI Shifter/Buffer is enabled and full.
