External Flash Memory Programming Control
In-circuit programming (ICP) via USB cable can be achieved by directly controlling the flash address,
control registers and P1 of FT8032 (P1 are used for flash data port). When host sends special
commands for programming flash contents, the firmware can use flash address registers for intended
address, port1 of FT8032 for intended data and flash control register for read/write control. The starting
address of USB firmware code should be located at “0000h” in the external flash, and 1394 firmware
code should be at “8000h”.
