Note
Connect this pin when the system clock is supplied from the dedicated flash programmer. If a resonator
is already connected to the X1 pin, the CLK pin does not need to be connected.
Caution The V
DD0
and V
DD1
pins, if already connected to the power supply, must be connected to the V
DD
pin of the dedicated flash programmer. When using the power supply connected to the V
DD0
and
V
DD1
pins, supply voltage before starting programming.
If Flashpro III/Flashpro IV is used as a dedicated flash programmer, the following signals are generated for the
µ
PD78F0354, 78F0354Y. For details, refer to the manual of Flashpro III/Flashpro IV.
