TMP86FS64FG
20.6.1 Flash Memory Erasing Mode (Operating command: F0H)
Note 1: “xxH
× 3” indicates that the device enters the halt condition after transmitting 3 bytes of xxh.
Note 5: Do not transmit the password string for a blank product.
Note 6: When a password error occurs, TMP86FS64FG stops UART communication and enters the halt mode. Therefore, when a
password error occurs, initialize TMP86FS64FG by the RESET pin and reactivate the serial PROM mode.
Note 7: If an error occurs during transfer of a password address or a password string, TMP86FS64FG stops UART communica-
tion and enters the halt condition. Therefore, when a password error occurs, initialize TMP86FS64FG by the RESET pin
and reactivate the serial PROM mode.
Description of the flash memory erasing mode
1. The 1st through 4th bytes of the transmitted and received data contain the same data as in the flash
memory writing mode.
