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 20.1). 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 FWP and MD3-MD0 as shown in table 3.1. 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.
20.1
• Module Standby Mode Setting
Access to the on-chip ROM can be enabled/disabled by the module standby control register
(MSTCR1). The initial value enables the on-chip ROM operation. On-chip ROM access is
disabled by setting the module standby mode. For details, see section 24, Power-Down Modes.
