The control afforded by the output enable signals using the boundary scan register and the EXTEST
instruction requires a compatible circuit board test environment to avoid configurations that could damage
the device. The user must avoid situations in which the MCF5272 output drivers are enabled into actively
driven networks. Overdriving the TDO driver when it is active is not recommended.
21.7
In non-IEEE 1149.1 operation, IEEE 1149.1 test logic must be made transparent to system logic by forcing
the TAP controller into test-logic-reset state, which takes at least five consecutive TCK rising edges with
TMS high. TMS has an internal pull-up resistor and may be left unconnected.
If TMS is unconnected or connected to V
regardless of the TCK state. This requires the TMS, TCK, and TDI inputs to be high.
