PRINCIPLES OF OPERATION
digital control registers
The THS1041 contains two clamp registers and a control register for user programming of THS1041 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. The clamp registers and control registers are write only registers,
and stored values cannot be read on the I/O data bus.
