6.6.10. Characteristics of the JTAG Interface
TCK
Clock signal of the Test-Access Port. It is used to syn-
chronize all JTAG functions. When JTAG operations are
not being performed, this pin should be driven to VSS.
The input stage of the TCK uses a TTL Schmitt Trigger.
TMS, TDI
Test Mode Selection and Test Data Input. Both signals
are inputs with a TTL compatible input specification. To
comply with JTAG specification they use pull-ups at their
input stage. The input stage of the TMS and TDI uses a
TTL Schmitt Trigger.
TDO
Test Data Output. This signal is multiplexed with the
function ALPHA. The output specification conforms to
the specification of the TTL output driver type B.

V
A special VDD, VSS supply is used only to support the digital output pins. This means inherently that in case of tristate conditions, external
sources should not drive these signals above the voltage PVDD which supplies the output pins.
