READI Module
24.15 Power Management
This section details the power management features of the READI module.
The READI module is a development interface, and is not expected to function under normal
(non-development) conditions. Therefore power management is required to reduce and minimize power
consumption during normal operation of the part.
24.15.1 Functional Description
The following are the candidates for power management:
24.15.2 Low Power Modes
When the MCU is in sleep, deep-sleep, or low power-down mode, all internal clocks on the MCU are shut
down, including the MCKO. The MSEO signal will be held negated.
Low power mode entry for the MCU will be held off until the READI module has transmitted all existing
messages (in the queues and transmit buffers). During this time, input messages from the development tool
are ignored.
Upon restoration of clocks in normal mode, program and data traces will be synchronized, if enabled.

If EVTI is negated at negation of RSTI, the READI module will be
disabled. No trace output will be provided, and output auxiliary port
will be three-stated.
All outputs will be held static.
Output auxiliary signals will be three-stated.
