3. PROGRAMMING FLASH MEMORY (
μ
PD70F3035A, 70F3035AY ONLY)
There are the following two methods for writing a program to the flash memory.
(1) On-board programming
Write a program to the flash memory using a dedicated flash programmer after the
μ
PD70F3035A and
70F3035AY have been mounted on the target board. Also mount a connector, etc. on the target board to
communicate with the dedicated flash programmer.
(2) Off-board programming
Write a program using a dedicated adapter before the
μ
PD70F3035A and 70F3035AY have been mounted on
the target board.
3.1 Selecting Communication Mode
To write the flash memory, use a dedicated flash programmer and serial communication. Select a serial
communication mode from those listed in Table 3-1 in the format shown in Figure 3-1. Each communication mode is
selected by the number of V
PP
pulses shown in Table 3-1.
