Example Of Serial Programming Connection (When User Power Supply Is Used) - Fujitsu F2MC-16LX Hardware Manual

24.2 Example of Serial Programming Connection
(When User Power Supply Is Used)
Figure 24.2-1 shows an example of serial programming connection when the power
supply voltage of the microcontroller is supplied from the user power supply. Mode
pins MD2, MD1, and MD0 are set to "011" to set internal vector modes (single-chip
mode, internal ROM external bus mode).
