Table 20. Conversion Command Summary
Panel Setup and
Measurement Commands
TSC conversion commands are only to be used in
direct conversion mode (AUTO = 0). Conversion com-
mands issued during autonomous mode are ignored.
All panel setup and measurement operations are auto-
mated when in autonomous mode (AUTO = 1).
Commands must be issued in write mode to be execut-
ed. There are two types of commands: panel setup reg-
isters (0x6x) and measurement/conversion registers
(0x7x). All measurement commands indicate that the
ADC is used and the ADC can begin to power up once
the 0x7x header has been recognized. All measure-
ment commands modify the target data register upon
the conclusion of the measurement command. The
CONT bit impacts the setup of the panel and ADC fol-
lowing the command. For panel setup commands and
combined commands, the user setting of this bit (R0) is
ignored. For these commands, the internal assumption
is shown in parentheses in Table 22.
The CONT bit impacts the setup of the panel and/or ADC
following the command (see command descriptions for
details). For some commands, the user setting of this bit
(R0) is ignored; for these commands the internal
assumption is shown in parentheses in Tables 8 and 22.
By definition, panel setup and measurement com-
mands are NOT pairable in write mode as each com-
mand modifies the panel setting both during the
command and after it (based on conversion executions
and CONT bit settings).
Note 1: Both SPI and I2C interfaces use a 7-bit register address format. I2C interfaces should left-justify the 7-bit addresses given in
Table 20 (e.g., to access register 50h use the command byte construction {101_0000_X}, where X is a don't care).
Note 2: R0 bit is forced to 1 for panel setup commands, and forced to 0 for combined and AUX commands. For measurement com-
mands it is user selectable. CONT = 0 means perform a measurement without continuation, while CONT = 1 means perform a mea-
surement with continuation. Continuation mode maintains the present panel setup conditions after the conclusion of the
measurement, and can be useful when performing multiple measurements of the same type.
