This LSI is available with 256 Kbytes of on-chip mask ROM. The on-chip ROM is connected to
the CPU, direct memory access controller (DMAC), and data transfer controller (DTC) through a
32-bit data bus (figure 24.1). The CPU, DMAC, and DTC can access the on-chip ROM in 8, 16
and 32-bit widths. Data in the on-chip ROM can always be accessed in one cycle.
The operating mode determines whether the on-chip ROM is valid or not. The operating mode is
selected using mode-setting pins FEW, MD1, and MD0. If you are using the on-chip ROM, select
mode 2 or mode 3; if you are not, select mode 0 or 1. The on-chip ROM is allocated to addresses
H'00000000 to H'0003FFFF of memory area 0.
