The following I²C scripts sets four devices for shared TDM mode, after devices are reset:

# Key: w NN YY ZZ ==> write to I2C address 0xNN, to register 0xYY, data 0xZZ
#               # ==> comment delimiter
#
# I2C programming script for four devices sharing a TDM bus
#  U4(SDOUT) -> U3 (SDOUT) -> U2 (SDOUT) -> U1 (SDOUT) -> Host Processor
