19. Serial PROM Mode
19.1
19.2
ROM is available in the serial PROM mode, and controlled by TEST, BOOT and RESET pins. Communication is
performed via UART. The serial PROM mode has seven types of operating mode: Flash memory writing, RAM loader,
Flash memory SUM output, Product ID code output, Flash memory status output, Flash memory erasing and Flash
memory security program setting. Memory address mapping in the serial PROM mode differs from that in the MCU
mode. Figure 19-1 shows memory address mapping in the serial PROM mode.
The TMP86FH92DMG has a 2048 byte BOOTROM (Mask ROM) for programming to flash memory. The BOOT-
The Figure 19-1 shows memory mapping in the Serial PROM mode and MCU mode.
In the serial PROM mode, the BOOTROM (Mask ROM) is mapped in addresses from 7800H to 7FFFH.
Note:Though included in above operating range, some of high frequencies are not supported in the serial PROM mode.
