TMP86FS49AIUG
20.3 Serial PROM Mode Setting
20.3.1 Serial PROM Mode Control Pins
To execute on-board programming, activate the serial PROM mode. Table 20-2 shows pin setting to activate
the serial PROM mode.
Note: The BOOT pin is shared with the UART communication pin (RXD1 pin) in the serial PROM mode. This pin is used as UART
communication pin after activating serial PROM mode
20.3.2 Pin Function
In the serial PROM mode, TXD1 (P02) and RXD1 (P01) are used as a serial interface pin.
Note 1: During on-board programming with other parts mounted on a user board, be careful no to affect these communication
control pins.
Note 2: Operating range of high frequency in serial PROM mode is 2 MHz to 16 MHz.
