Using the EXTEST instruction requires a circuit-board test environment that avoids
device-destructive configurations in which MCU output drivers are enabled into actively driven
networks.
Low-power stop mode considerations:
29.5.2 Nonscan Chain Operation
Keeping the TAP controller in the test-logic-reset state ensures that the scan chain test logic is
transparent to the system logic. It is recommended that TMS, TDI, TCLK, and TRST be pulled
up. TRST could be connected to ground. However, since there is a pull-up on TRST, some amount
of current results. The internal power-on reset input initializes the TAP controller to the
test-logic-reset state on power-up without asserting TRST.
Freescale Semiconductor
• The TAP controller must be in the test-logic-reset state to either enter or remain in the
• The TCLK input is not blocked in low-power stop mode. To consume minimal power, the
• The TMS, TDI, and TRST pins include on-chip pull-up resistors. For minimal power
low-power stop mode. Leaving the test-logic-reset state negates the ability to achieve
low-power, but does not otherwise affect device functionality.
TCLK input should be externally connected to V
consumption in low-power stop mode, these three pins should be either connected to V
or left unconnected.
