1. When using the boundary scan function, clear TRST to 0 at power-on and after the t
2. The following must be noted on the power-on reset signal applied to the TRST pin.
3. TCK clock speed should be slower than system clock frequency.
4. In serial communication, data is input or output from the LSB as shown in figure 13.5.

when the boundary scan function is not used, set TCK, TMS, and TDI to Hi-Z, clear TRST to 0

pulled up internally, so care must be taken in standby mode because breakthrough current flow
can occur if there is a potential difference between the pin input voltage value when set to 1
and the power supply voltage Vcc.
• Reset signal must be applied at power-on.
• TRST must be separated in order not to affect the system operation.
• TRST must be separated from the system circuitry in order not to affect the system
• System circuitry must also be separated from the TRST in order not to affect TRST
operation.
