以下 I²C 脚本在器件复位后将四个器件设置为菊花链 TDM 模式：

# Key: w NN YY ZZ ==> write to I2C address 0xNN, to register 0xYY, data 0xZZ
#               # ==> comment delimiter

# I2C programming script for four devices in daisy chain TDM mode
#  U4(DOUT) -> (GPIO1) U3 (DOUT) -> (GPIO1) U2 (DOUT) -> (GPIO1) U1 (DOUT) -> Host Processor
