- UREGC pin voltage levels (RL78/L1C only)
UREGC pin voltage level on QB-RL78L1C differs from the target device.
Target device: 3.3V
QB-RL78L1C: Open
- 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 differs from that of the target device.
Refer to a device user’s manual about the pins which setting is possible to a TTL buffer.
