Note 1: When a user program is downloaded from UART and USB is used in the system, the pull-up resistor for
Note 2: When a user program is downloaded via USB, do not start the UART application software on the PC.
Note 3: When a user program is downloaded via UART, do not connect a USB connector.
Note 4: When USB is not used, the D+ and D- pins must be pulled up or down to prevent flow-through current.

Connect to the level shifter.
No special setting is needed
for booting via UART.
If USB is not used, add a
pull-up or pull-down resistor to
prevent flow-through current
on the D+/D- pins.

Method
No special setting is needed
for booting via USB.
Add a pull-up resistor (100
kΩ r ecommended) to prevent
transition to UART processing.
Connect to the USB connector
by adding a dumping resistor
(27Ωrecommended) and a
programmable pull-up resistor
(1.5 kΩrecommended). When
USB is not accessed, the pin
level should be fixed with a
resistor to prevent
flow-through current.
Connect to the USB connector
by adding a dumping resistor
(27Ω recommended). When
USB is not accessed, the pin
level should be fixed with a
resistor to prevent
flow-through current.
This pin is used to control
ON/OFF of the D+ pin’s
pull-up resistor. Add a switch
externally so that the pull-up is
turned on when “1”. Reset sets
this pin as an input port, so
add a pull-down resistor
(100kΩ recommended).
