15. Serial PROM Mode
15.1 Outline
15.2 Memory Mapping
BOOTROM is available in the serial PROM mode, and controlled by TEST, BOOT and
tion 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 eras-
ing and Flash memory read protection setting. Memory address mapping in the serial PROM mode differs from that
in the MCU mode. Figure 15-1 shows memory address mapping in the serial PROM mode.
The TMP86F409NG has a 2048 byte BOOTROM (Mask ROM) for programming to flash memory. The
Note: Though included in above operating range, some of high frequencies are not supported in the serial PROM mode. For
The Figure 15-1 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.
