GND Ground
Notes 1. When using the clock out of the flash programmer, connect CLK of the programmer to X1, and connect
its inverse signal to X2.
2. Flashpro III only
Cautions 1. Be sure to connect the REGC pin in either of the following ways.
• To GND via a 1
• Directly to V
2. When connecting the REGC pin to GND via a 1
from the CLK pin of the flash programmer.
Create an oscillator on the board to supply a clock.
