2. Serial PROM Mode
2.1
Outline
The TMP86FS27 has a 2-Kbyte BOOT ROM for programming to flash memory. This 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 TEST pin and RESET pin and P00 and P01
pin, and is communicated with UART. There are four operation modes in a serial PROM mode:
flash memory 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 2.1.1.
Table 2.1.1 Operating Area of Serial PROM Mode
2.2
Memory Mapping
The BOOT ROM is mapped in address F800H to FFFFH. The BOOT ROM can’t be accessed in
MCU mode. The Figure 2.2.1 shows a memory mapping.
