reducing current consumption
240x DSPs incorporate a unique method to reduce the device current consumption. A reduction in current
consumption can be achieved by turning off the clock to any peripheral module which is not used in a given
application. Table 17 indicates the typical reduction in current consumption achieved by turning off the clocks
to various peripherals. See the TMS320LF/LC240xA DSP Controllers Reference Guide: System and
Peripherals (literature number SPRU357) for further information on how to turn off the clock to the peripherals.

This number represents the current drawn by the digital portion of the ADC module.
Turning off the clock to the ADC module results in the elimination of the current drawn
by the analog portion of the ADC (ICCA) as well.

signal transition levels
The data in this section is shown for the 3.3-V version. Note that some of the signals use different reference
voltages, see the recommended operating conditions table. Output levels are driven to a minimum logic-high
level of 2.4 V and to a maximum logic-low level of 0.4 V.
Figure 24 shows output levels.
