- The detection voltage value of the voltage detector (LVD)
The V
value of the detection voltage differs from that of the target device.
LVIH
.
- LCD controller/driver behavior
When executing STOP instruction or an instruction which stops the main system clock (fMAIN) with setting the
main system clock (fMAIN) to an operation clock of LCD controller/driver, LCD controller/driver stops execution on
target device.
On the other hand, it continues execution on IECUBE. LCD controller/driver differ from that of the target device.
- Capacitor which is mounted on user system when LCD controller/driver is used
The following capacitors are mounted on IECUBE internal circuit.
Because of this, terminal characteristic on IECUBE is slightly different from target device.
Mounting point : Between VL1 and GND terminals, Between VL2 and GND terminals,
Mounted condenser capacity : 0.1uF
- A/D conversion error around 0[V] and 5.5[V]
A/D conversion error around 0[V] and 5.5[V] on IECUBE is big.
Use on-chip debugging or actual equipment for checking A/D conversion in 0.1[V] and under, or 5.36[V] and over.
