3.2.1 Sleep Mode Activity Overview

A clarification has been made to Table 12-2 Sleep Mode Activity Overview, where the single table has been split into three separate tables for clarity. Functional changes are shown in bold.

Note:
  1. The RUNSTBY bit of the corresponding peripheral must be set to enter the active state.
  2. PIT only.

Note:
  1. The RUNSTBY bit of the corresponding peripheral must be set to enter the active state.
  2. PIT only.
  3. The BOD oscillator runs only in Sampled mode.

Note:
  1. The I/O pin must be configured according to Asynchronous Sensing Pin Properties in the PORT section.
  2. The RUNSTBY bit of the corresponding peripheral must be set to enter the active state.
  3. PIT only.
  4. When the RUNSTDBY bit is set, the AC will operate without updating its Status register or triggering interrupts. If another peripheral has requested CLK_PER, the AC will use the clock to update the Status register and trigger interrupts.
