Chapter 5 Restrictions - NEC IE-78K0-NS-P04 Preliminary User's Manual

1. Starting up the IE system without target board connected makes initial values for ports-indefinite.
2. The RESET value of the IF-REG (F801h) register is not correct. The reset value will be correct after
the clock of the VANUDL is enabled.
3. LCD-controller/driver differences.
There are different LCD-controller/driver macro's used on the device and the emulation board (IE-
78K0-NS-P04). Due to this there are differences in the initialisation of the special function register
(SFR) for the LCD-controller driver.
In the following there is the description of the configuration of the LCD-controller/driver control regis-
ters as they are implemented on the emulation of the µ1615A Subseries and the devices of the
µ1615A Subseries. These registers have to be set based on the configuration of the application.
