IO_CONTROL_2 REGISTER

RS[5:0] = 0, 0, 0, 1, 0, 0

Power-On/Reset = 0x0000

Table 69 outlines the bit designations for the register. Bit 15 is the first bit of the data stream. The number in parentheses indicates the

power-on/reset default status of that bit. The internal bias voltage can be enabled on multiple channels.
