to prevent overlap current to unused ports. (All port inputs and peripheral function inputs shared with the ports become
invalid.) Therefore, to access to the flash memory in the RAM loader mode without UART communication, port inputs
must be valid. To make port inputs valid, set the pin of the port input control register (SPCR) to “1”.
In the flash memory erasing mode, the erasure area of the flash memory is specified by n−2 byte data.
The start address of an erasure area is specified by ERASTA, and the end address is specified by ERAEND.
If ERASTA is equal to or smaller than ERAEND, the sector erase (erasure in 4 kbyte units) is executed. Executing
If ERASTA is larger than ERAEND, the chip erase (erasure of an entire flash memory area) is executed and the
In the serial PROM mode, the input level is fixed to the all ports except P00 and P01 ports with a hardware feature
The SPCR register is not operated in the MCU mode.
Note:When the sector erase is executed for the area containing no flash cell, TMP86FH92DMG stops the UART
