10.8 GET_CONFIG_PAGE
This command has three functions:
P1 and P0 select one of four configuration pages. The response (X3 X2 X1 X0 D3 D2 D1
D0) contains the contents of the selected configuration page in its lower nibble. For P = 0
or P = 1 the higher nibble reflects the current setting of N (the transmit pulse width). For
P = 2 or P = 3 the system status information is returned in the higher nibble.

When ACQAMP is set, the actual amplitude of the data
signal is stored as reference. After resetting ACQAMP
status bit AMPCOMP is set when the actual data signal
amplitude is higher than the stored reference.
