DESCRIPTION
The DMC42P1106 is a system evaluation LSI
having a built in One-Time Programming circuit.
A programming and verification for the internal
EPROM is achieved by using a general EPROM
programmer with an adapter socket.
The function of this device is exactly same as
the DMC42C1106 with programming of the internal
