Operation

The on-chip ROM is connected to the CPU by a 16-bit data bus, and both byte and word data can

be accessed in one state. Even addresses are connected to the upper 8 bits, and odd addresses to

the lower 8 bits. Word data must start at an even address.

The on-chip ROM is enabled and disabled by setting the mode pins (MD2, MD1, and MD0). These

settings are shown in table 18.1.

In normal mode, a maximum of 56 kbytes of ROM can be used.
