3.3.1 Low Power Modes
There are two specific low power modes available that can be configured to allow TX62/TX82
to save power - SLEEP mode (Section 3.3.1.1) and SUSPEND mode (Section 3.3.1.2).
Figure 38 illustrates how the module transits between its operating modes including SLEEP
and SUSPEND modes.
Figure 38: Low power modes with state transitions
Notes:
• When all serial interfaces (i.e. ASC0, and ASC1) are idle, the module can enter SLEEP or
SUSPEND mode depending on additional configuration settings.
• The serial interfaces are not idle if there is any response message not read out from any of
them.
