Table 5-1 is an example script for TAx5xxx-Q1 devices under the parameters outlined in the application example section.

EVM 1 example script:

# Key: w a0 XX YY ==> write to I2C address 0xa0, to register 0xXX, data 0xYY
# # ==> comment delimiter
#
# The following list gives an example sequence of items that must be executed in the time
# between powering the device up and reading data from the device. Note that there are
# other valid sequences depending on which features are used.
#
# See the corresponding EVM user guide for jumper settings and audio connections.
#
# Line-Out Fully-Differential 2-channel : INP1/INM1 - Ch1, INP2/INM2 - Ch2
# FSYNC = 48 kHz (Output Data Sample Rate), BCLK = 12.288 MHz (BCLK/FSYNC = 256)
