QB-RL78L12 In-Circuit Emulator
- P122 pin input characteristics
The input characteristics of the P122 pin differ between the target device and emulator.
Target device
IECUBE
- Power-on-reset (POR) voltage value
The power-on-reset (POR) voltage value differs from that of the target device.
Target device
IECUBE
- 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 4-3 for
details. The following pins can be set for the TTL buffer.
