APPLICATION

2.14.4 Parallel I/O mode

In the parallel I/O mode, program/erase to the built-in flash memory can be performed by a flash programmer

(MFW-1).

The memory area of program/erase is from 0F00016 to 0FFFF16 (boot ROM area) or from 0800016 to

0FFFF16 (user ROM area). Be especially careful when erasing; if the memory area is not set correctly, the

products will be damaged eternally.

Table 2.14.1 shows the setting of programmers when programming in the parallel I/O mode.

2.14.5 Standard serial I/O mode

Table 2.14.2 shows a pin connection example (4 wires) between the programmer (MFW-1) and the

microcomputer when programming in the standard serial I/O mode.

38K2 Group flash memory version

Notes 1: When connecting a serial programmer, first connect both GNDs to the same GND level.

2: VCC power of MFW-1 is supplied from a target board. Power consumption of MFW-1 is Max. 200

mA when serial programming. Therefore, when the current capacity of target borad is short,

connect AC adapter and supply power source to MFW-1.
