*1) Pin Type
I: Input, O: Output, I/O: Input/Output, S: Supply, N/A: Not Applicable
*2) Connect either SPI or UART but not both. Connecting both SPI and UART at the same time may result in malfunction of the
device. Regarding unused pin, please connect /CS pin to VCC and all other unused input pins to GROUND.
*3) Regarding Pin function selection, please refer to the DRDY_ON at register MSC_CTRL[0x02(W1)],bit[2]
*4) Regarding Pin function selection, please refer to the EXT_SEL at register MSC_CTRL[0x02(W1)],bit[7:6]
*5) Regarding BaudRate setting, please refer to the BAUD_RATE at register UART_CTRL[0x08(W1)],bit[9:8]. Change the BRATE
pin when the power for the IMU is OFF, or perform a hardware reset after the BRATE pin is changed.
*6) If the /RST pin is not used, keep the pin at High (VCC) voltage level.
Note) All input pins have weak pull up resistors inside the IMU.
