231 / 272 page  Page 219 TMP86FS28DFG 18. Serial PROM Mode 18.1 Outline The TMP86FS28DFG has a 2048 byte BOOTROM (Mask ROM) for programming to flash memory. The BOOTROM is available in the serial PROM mode, and controlled by TEST, BOOT and RESET pins. Communica- tion is performed via UART. The serial PROM mode has six types of operating mode: Flash memory writing, Flash memory SUM output, Product ID code output, Flash memory status output, Flash memory erasing and Flash mem- ory read protection setting. Memory address mapping in the serial PROM mode differs from that in the MCU mode. Figure 18-1 shows memory address mapping in the serial PROM mode. Note: TMP86FS28DFG doesn’t support RAM loader mode. (The RAM loader mode can’t be used in TMP86FS28DFG.) Note: Though included in above operating range, some of high frequencies are not supported in the serial PROM mode. For details, refer to “Table 18-5”. 18.2 Memory Mapping The Figure 18-1 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. The flash memory is divided into two banks for mapping.
