MC44BS373CA Data Sheet
I2C Programming
Table 15 lists the UHF settings used.
Table 16 lists the other settings used.
Table 17 lists settings of fields X2, X1, and X0, used to set the device into test mode 1 and to control the
VHF range.
NOTE
Test modes 1 and 2 are intended for manufacturing test purposes only and
cannot be used for normal applications, except for VHF range (states 1.b
to 1.e).
