control register
The TLV1562 is software configurable. The first two bits, MSBs (D9,8), are used to address the register set. The
rest of the 8 bits are used as data. There are two control registers, CR0 and CR1, for user configuration. All of
these register bits are written to the control register during a write cycle. A description of the control registers
and the input/output data formats are shown in Figure 1.

NOTE:
Channel select bits CR0.(1,0), CS(1,0) are ignored when the device is in the dual (interrupt or
continuous) modes using differential inputs, since both differential input pairs are automatically
selected. CR0.0 (i.e., CS0 bit) is used to determine if channels 1 and 3 or channels 2 and 4 are
selected if single-ended input mode is used.
