1. A reset must always be executed by driving the ETRST pin to 0, regardless of whether or not
2. The following must be considered when the power-on reset signal is applied to the ETRST pin.
3. The registers are not initialized in standby mode. If the ETRST pin is set to 0 in standby mode,
4. The frequency of the ETCK pin must be lower than that of the system clock. For details, see
5. Data input/output in serial data transfer starts from the LSB. Figure 21.4 and 21.5 shows
6. When data that exceeds the number of bits of the register connected between the ETDI and
7. If the JTAG serial transfer sequence is disrupted, the ETRST pin must be reset. Transfer

details, see section 25, Electrical Characteristics. To activate the JTAG after a reset, drive the
ETRST pin to 1 and specify the ETCK, ETMS, and ETDI pins to any value. If the JTAG is not
to be activated, drive the ETRST, ETCK, ETMS, and ETDI pins to 1 or the high-impedance
state. These pins are internally pulled up and are noted in standby mode.
The reset signal must be applied at power-on.
