20. Flash Memory
write and erase operations to the flash memory are controlled in the following three types of mode.
This chapter describes how to access the flash memory using the flash memory control register (FLSCR) in the MCU
and serial PROM modes.
TMP88FW45AFG has 122880 bytes flash memory (address: 04000H to 21EFFH and FFF00H to FFFFH). The
In the MCU and serial PROM modes, the flash memory control register (FLSCR) is used for flash memory control.

MCU mode
correction and firmware change after shipment of the device since the write operation to the flash memory
is available by retaining the application behavior.
Serial PROM mode
(UART) enables the flash memory to be controlled by the small number of pins. TMP88FW45AFG in the
serial PROM mode supports on-board programming which enables users to program flash memory after the
microcontroller is mounted on a user board.
Parallel PROM mode
program writer provided by the third party. High-speed access to the flash memory is available by controlling
address and data signals directly. For the support of the program writer, please ask Toshiba sales represen-
tative.
The flash memory is accessed by the CPU control in the MCU mode. This mode is used for software bug
The flash memory is accessed by the CPU control in the serial PROM mode. Use of the serial interface
The parallel PROM mode allows the flash memory to be accessed as a stand-alone flash memory by the
