† Number of modes refers to total possible modes for that configuration: includes noninverting or inverting and number
of codes (train).
‡ X = don’t care and can be held high or low, I = 1 inverting, I = 0 for noninverting
The multitude of transmit and receive configurations are discussed in subsection 5.10.3 and Section 5.12.
A reference for the quick, correct programming of the device in the desired mode and configuration is
discussed in Section 5.12. Table 5–4 lists the signals required to set the amplifier test, program, and read
modes.
