18-6-3 Circuit Requirements for the Target Board
(in Clock Synchronous Communication using the PanaX Se-
rial Writer)
In programming Flash EEPROM using the PanaX serial writer, you need not to write load program in
advance and also be able to use all space of the Flash EEPROM as user program area.
Use P53, P54 for communication with serial writer.
This section describes the circuit requirements for the target board for onboard serial programming in
clock synchronous communication using the PanaX Serial Writer.
