Specifications of the External Trigger Inputs and Outputs
Table 1-4 Specifications of the External Trigger Inputs and Outputs
Input signal channels
E2 expansion interface: 2 (ch. 0: pin 11, ch. 1: pin 12)
Output signal channels
E2 expansion interface: 2 (ch. 0: pin 9, ch. 1: pin 10)
Voltage of the E2 expansion
interface
•
When the power is supplied from the emulator: voltage to be supplied
(any voltage from 1.8 V to 5.0 V, as specified in the debugger)
•
When the power is not supplied from the emulator: VDD voltage
Conditions for detecting an
external trigger input
Detecting edges (rising, falling, or both)
Detecting a level (low or high)
Operation during the input of an
external trigger
Break
*
Recording the data from measuring the current consumption while the low
or high level is being input
Condition for detecting an
external trigger output
Detecting a break or a trigger condition for measuring the current
consumption
Operation during the output of
an external trigger
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
s to 65535
s).
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
s to 65535
s). Otherwise, a high level is output while
a condition is being satisfied.
Note: About 12
s will be required from the detection of a condition for an external trigger input being satisfied until the
user program is stopped.
