Figure 1040.Cpa State Entry From The Spa State With Continued Online Operation - STMicroelectronics SPC572L series Reference Manual

IEEE 1149.7 Compact JTAG Test Access Port Controller (CJTAG)
fully utilized. This has significance when the SP contains control information that allows the
STL to stall the completion of a SP.
Figure 1040. CPA State Entry from the SPA State with Continued Online Operation
When an unsupported feature is enabled, the TAP.7 controller is placed offline. This
suspends the TAP.7 controller's operation at a point where its operation may later be
synchronized to the remainder of the system. The APU stops advancing the EPU's and
CLTAPC's TAPC state machine state while offline. It also suspends Data Channels activity
while offline. The detection of the appropriate Online Activation Protocol while the TAP.7
controller is offline places the TAP.7 controller online and causes an exit from the CPA state
