MC44BS373CA Data Sheet
I2C Programming
Table 18 lists settings of fields X5, X4, and X3, used to set the device into test mode 2.
Table 19 lists settings of fields Y2, Y1, and OOR, used to set the device into READ mode and to determine
RF oscillator out-of-frequency range information.

Transient output inhibit disabled (that is, speed-up mode)
During this speed-up test mode, ATT = 0 forces sound current source to 1
A,
while ATT = 1 forces it to 10
