PRINCIPLES OF OPERATION
digital control registers
The THS1031 contains two clamp registers and a control register for user programming of THS1031 operation.
Binary data can be written into these registers by using pins I/O0 to I/O9 and the WR and OE pins (see the
previous section). In input mode, the two I/O bus MSBs are address bits, 00 addressing clamp register 1, 01
clamp register 2, and 10 the control register.
