Input selector control register
The write only, two byte, input selector control register is
located on absolute address 0FFFH (4095) and consists
of 16 bits, starting with bit 0 and ending with bit 15.

By making the I
acknowledge pulse (see Fig.11). The delay should be
larger than or equal to 1/f
sampling frequency.
By not using the auto-increment feature. This means
that each data word must be preceded by its intended
destination address.
