18. Flash Memory
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.
Note 1: The 'Read Protect' described by data sheet of old edition was changed into 'Security Program'.
TMP86FH92DMG has 16384byte flash memory (address: C000H to FFFFH). The write and erase operations to

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. TMP86FH92DMG 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.
