CONTROL BYTE
The control byte (on SDI), as shown in Table 2, provides the start conversion, addressing, A/D converter
resolution, configuration, and power-down of the TSC2008-Q1. Figure 31, Table 2, and Table 3 give detailed
information regarding the order and description of these control bits within the control byte.

DESCRIPTION
Start Bit. When this bit = '1', it indicates this is one of the user commands. A new control byte can start every 16th clock cycle in

12-bit conversion mode or every 12th clock cycle in 8-bit conversion mode (see Figure 31 through Figure 34).

These bits configure the pull-up resistor value, control the filter bypass, and select the SDO output timing. The bits are static and the
values are stored in register bits that will only be reset to default by a reset condition (power-on reset, software reset, or SureSet) or
changed with the setup command.
