BOOT ROM is a mask ROM that contains a program to write the FLASH memory on board.
The BOOT ROM is available in a serial PROM mode and it is controlled by P11 pin, BOOT
pin (P23), TEST pin and
pins. There are four operation modes in a serial PROM mode: FLASH writing mode, RAM
loader mode, FLASH memory SUM output mode and product discrimination code output
mode. Operating area of serial PROM mode differs from that of MCU mode. The operating
area of serial PROM mode shows in Table 2.18.1.
