3.1 Selection of Communication System
of the communication modes listed in Table 3-1. Base your selection of the communication mode on the selection
format shown in Table 3-1. Refer to the number of V
mode.
CSI0
UART0
The following two flash memory programming methods are available.
Writing to the flash memory is done via serial communication using the dedicated flash programmer. Select one
The program is written to the flash memory using a dedicated flash programmer after the PD70F3102-33 is
mounted on the target board. Install the connectors, etc., required for communication with the dedicated flash
programmer, on the target board.
The program is written to the flash memory using a dedicated adapter before the PD70F3102-33 is mounted on
the target board.
