Default Description
000 Compare command. Determines whether the peak value or
the current value of the Termination Fault counters is read in
registers 0Ah-0Dh.
000: Resets compare value to 00; registers 0Ah-0Dh all show
current counter values. Sets detection to look for MAX peak
values.
001: Capture counter 0. Register 0Ah shows peak value.
010: Capture counter 1. Register 0Bh shows peak value.
011: Capture counter 2. Register 0Ch shows peak value.
100: Capture counter 3. Register 0Dh shows peak value.
101: Resets compare value to 1Fh. Sets detection to look for
MIN peak values.

010 Part Identifier. Note that single output devices (LMH0303)
have the LSB=1. Dual output devices (LMH0307) have the
LSB=0.

00000 This is either the current value of TF Counter 0 P, or the peak
value of the counter, depending on CMPCMD in register 08h.
