tuning of current
consumption
Supported Supported
Current consumption by the user system is
measured when the power is supplied from
the E2.

Supported
Supported
External triggers can be input to or output
from the E2 expansion interface.
Notes: 1. Only devices in which the trace function was implemented.
2. The trace function is not supported in an RL78/G14 MCU whose ROM size is 64 Kbytes or less. The trace
function is also not supported for RL78/G11, RL78/G1G, and RL78/FGIC MCUs.
3. Only RL78/F1x series(except F12), RL78/F2x
