For example, if erroneous operation occurs with a wait time setting of 16 states, check the
operation with a wait time setting of 1,024 * states or more.
If the same kind of erroneous operation occurs after a reset as after a state transition, hold the RES
pin low for a longer period.
Note: * This figure applies to the H8/38024, H8/38024S, and H8/38024R Groups. The number of

When using the HD64F38024, the oscillators may not operate if an initial voltage of 10 mV is
applied to the V
the oscillation control signals. It can be corrected by cutting off power and allowing the V
voltage to drop to ground potential before powering-on once again.

When using the on-chip emulator, system clock precision is necessary for programming or erasing
the flash memory. However, the on-chip oscillator frequency can vary due to changes in
conditions such as voltage or temperature. Consequently, even if the on-chip oscillator is selected
when using the on-chip emulator, pins OSC1 and OSC2 should be connected to an oscillator, or an
external clock should be supplied. In this case, the LSI uses the on-chip oscillator when user
programs are being executed and the system clock oscillator when programming or erasing flash
memory. The process is controlled by the on-chip emulator.
