Note 1: Secondary function is selectable in
smart
BASIC application.
Note 2: DIO = Digital Input or Output. I/O voltage level tracks VCC.
Note 3: AIN = Analog Input
Note 4: DIO or AIN functionality is selected using the GpioSetFunc() function in
smart
BASIC.
Note 5: AIN configuration selected using GpioSetFunc() function.
Note 6: I2C, UART, SPI controlled by xxxOPEN() functions in
smart
BASIC.
Note 7: SIO_21 to SIO_24 are DIO by default when $autorun$ app runs on power up.
Note 8: RF_ANT pin (pin30) is on theBL600-ST module only. Customer MUST use 50-Ohm trace from
RF_ANT pin to RSMA RF connector on host PCB. More details on 50-Ohm trace design refer to
section
50-OhmsRF Trace on Host PCB for BL600-ST .
