本节提供了一个典型的 EVM I²C 寄存器控制脚本，其中显示了如何将 TAA3040 设置为八通道数字 PDM 麦克风录制模式。

# Key: w 98 XX YY ==> write to I2C address 0x98, 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 TAA3040EVM user guide for jumper settings and audio connections.
#
# PDM 8-channel : PDMDIN1 - Ch1 and Ch2, PDMDIN2 - Ch3 and Ch4, 
#                 PDMDIN3 - Ch5 and Ch6, PDMDIN4 - Ch7 and Ch8
# FSYNC = 44.1 kHz (Output Data Sample Rate), BCLK = 11.2896 MHz (BCLK/FSYNC = 256)
