Table 1-4 Specifications of the External Trigger Inputs and Outputs
Input signal channels
Output signal channels
Voltage of the E2 expansion
interface
Conditions for detecting an
external trigger input
Operation during the input of an
external trigger
Condition for detecting an
external trigger output
Operation during the output of
an external trigger
Note: About 100 µs will be required from the detection of a condition for an external trigger input being satisfied until
the user program is stopped.

Pin Nos. 1 to 8 are not used.
These pins must be left open-circuit.
External trigger output (ch. 0)
External trigger output (ch. 1)
External trigger input (ch. 0)

GND
A pin for output of the power-supply voltage for the E2 expansion interface
(1.8 V to 5.0 V)
E2 expansion interface: 2 (ch. 0: pin 11, ch. 1: pin 12)
E2 expansion interface: 2 (ch. 0: pin 9, ch. 1: pin 10)
When the power is supplied from the emulator:
•
• When the power is not supplied from the emulator: VDD voltage
Detecting edges (rising, falling, or both)
•
Detecting a level (low or high)
•
• Break*
• Recording the data from measuring the current consumption while the
low or high level is being input
Detecting a break or a trigger condition for measuring the current
consumption
When a break is detected, a low- or high-level pulse is output (the
•
pulse width can be set to times in the range from 1 µsec to 65535
µsec).
When a trigger condition for measuring the current consumption is
•
detected, a high-level pulse is output (the pulse width can be set to
times in the range from 1 µsec to 65535 µsec). Otherwise, a high level
is output while a condition is being satisfied.
