Jumper
PF6 is used as I2C standard mode and it is connected to
I2C2_SCL signal on Audio DAC, Audio external PLL,
temperature sensor and RF EEPROM connector when JP6 is
set as shown to the right (default setting):
JP6
PF6 is used as I2C fast mode and it is connected to
I2C2_SCL_F signal on EEPROM when JP6 is set as shown to

PA9 is connected to I2S_MCK signal on CS42L52 when JP18
is set as shown to the right (default setting)
JP18
PA9 is connected to IR_IN signal on TSOP34836 when JP18 is
set as shown to the right:
The I2C address of CS42L52 is 0b1001010, and that of External PLL CS2200 is
0b1001110.

USB

The STM32303E-EVAL evaluation board supports USB2.0 compliant full speed
communication via a USB type B connector (CN12). The evaluation board can be powered
by this USB connection at 5 V DC with 500 mA current.
A USB disconnection simulation can be implemented by controlling the 1.5 K pull-up resistor
on the USB+ line and by detecting the 5 V power on the USB connector (CN12) via a
resistor connected to PB8.
USB will work properly when VDD > 3 V.

RS232, RS-485 and IrDA

The RS232, RS-485 and IrDA communication is supported by D-type 9-pin RS232/RS-485
connectors (CN8) and IrDA transceiver (U10) which is connected to USART1 of
STM32F303VET6 on the STM32303E-EVAL evaluation board. Bootloader_RESET &
Bootloader_BOOT0 signals are added on the RS232 connector (CN8) for ISP support.
