QB-RL78F14 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-RL78F14
- The detection voltage value of the voltage detector (LVD)
The value of the detection voltage differs from that of target device.
.
- I/O port output signal level detection function
I/O port output signal level detection function emulation is not supported.
Even if you set as "Output data is read (PMS0=1)" at port mode select register (PMS), the value of the port
register (Pmn) is read.
Remark m = 0 to 8, 10 to 12, 14, 15, n = 0 to 7
- Oscillation stopped detection function
No supported. IECUBE cannot stop operation clock.
- RAM-ECC function
No supported.
