QB-RL78G1F In-Circuit Emulator
- TTL input buffer characteristics
If the port input mode register (PIM) is used to set the input of a pin that can be set for the TTL buffer to the TTL
level, the high-level input voltage characteristics differ between the target device and emulator. See Table 4-4
for details. The following pins can be set for the TTL buffer.
Target device
QB-RL78G1F
- The detection voltage value of the voltage detector (LVD)
LVD detection voltage differs from that of the target device.
