2.5.1
The MPC561/MPC563 has five JTAG signals. The test data input (TDI) and test data output (TDO) scan
ports are used to scan instructions as well as data into the various scan registers for JTAG operations. The
scan operation is controlled by the test access port (TAP) controller, which in turn is controlled by the test
mode select (TMS) input sequence. The scan data is latched at the rising edge of the test clock (TCK).
On the MPC561/MPC563, JTAG is used for boundary scan only. There is no access to internal
MPC561/MPC563 circuitry. When JTAG mode is enabled, the READI module will be held inactive. See
Figure 2-4
JTAG is entered by the following sequence of events:
JTAG mode is exited by:

Assert PORESET/TRST to reset the JTAG TAP controller
Hold JCOMP/RSTI high prior to PORESET/TRST negation and keep high as long as JTAG mode
is required
(The READI module will be held inactive since only one of the multiplexed functions JCOMP and
RSTI can be asserted at the negation of PORESET/TRST).
Drive JCOMP/RSTI low.
