2.13 Flash memory mode

This paragraph explains the registers setting method and the notes relevant to the flash memory mode of

M38049FFHSP/FP/HP/KP.

2.13.1 Overview

The functions of the flash memory version are similar to those of the mask ROM version except that the

flash memory is built-in and some of the SFR area differ from that of the mask ROM version (refer to

“2.13.2 Memory map”).

In the flash memory version, the built-in flash memory can be programmed or erased by using the following

three modes.

• CPU rewrite mode

• Parallel I/O mode

• Standard serial I/O mode

2.13.2 Memory map

M38049FFHSP/FP/HP/KP have 60 Kbytes of built-in flash memory.

Figure 2.13.1 shows the memory map of the flash memory version.
