Remark The operating frequency ratings of the PD78F0034A and the conventional products of the mask ROM
The PD78F0034B can use one channel (serial interface SIO30) as a handshake mode.
When main system clock is selected
When subsystem clock is selected
versions of the PD780024A, 780034A Subseries are the same. The operating frequency ratings of
the PD78F0034B and the expanded-specification products of the mask ROM versions of the PD780024A,
780034A Subseries are the same.
