Notes 1.
μ
PD78058 only
2.
When the external device expansion function is used with the
μ
PD78058, set the internal ROM capacity
to 56 Kbytes or less using the memory size switching register (IMS).
3.
The internal ROM capacity and internal high-speed RAM capacity depend on the products (see the next
table).
