Renesas M34502T-MCU Manual De Usuario

(1) External trigger signal input timing

The latch timing of the external trigger signal is shown in Figure 5.3.

(2) External trigger signal input characteristics

Trigger breaks work according to the condition (leading edge/trailing edge) of signals input from
the external trace cable. The external trigger signals of the trace points and the external trigger
signals of the break points use the same signals. The input characteristics of the external trigger
signals are shown in Table 5.4 below. See the table before using external trigger signals.

With the M34502T-MCU if any of the following restrictions applies, it is necessary to evaluate the
system by an evaluation MCU (OTP version).

(1) The system which uses RESET output cannot be evaluated.

(2) The system which uses low-power detection function cannot be evaluated.

(3) The operation cannot be checked by a power-on reset.

(4) After resetting, it is not possible to change to the ceramic oscillation or CR oscillation by starting

up from the on-chip oscillator. After resetting, the system operates by the system clock of the
M34502T-MCU.

(5) As the operating voltage of the M34502T-MCU is 3 V or 5 V, the results of the A-D conversion

may differ from the theoretical values because of the difference with the voltage of the target
system.

(6) With the M34502T-MCU, it is not possible to evaluate the system which uses the multi

comparator function for 4580 Group.
