3.1.1 Sleep Mode Activity Overview
A clarification has been made to Table 11-3 Sleep Mode Wake-up Sources. Functional changes are shown in bold.
Table 11-3. Sleep Mode Wake-up Sources
| Wake-Up Sources | Active in Sleep Mode | ||
|---|---|---|---|
| Idle | Standby | Power-Down | |
| PORT Pin Interrupt | X | X | X(1) |
| BOD VLM interrupt | X | X | X |
| RTC interrupts | X | X(2,3) | X(3) |
| TWIn Address Match interrupt | X | X | X |
| USARTn Start-of-Frame interrupt | - | X | - |
| TCBn interrupts | X | X(2) | - |
| ADCn/PTC(4) interrupts | X | X(2) | - |
| ACn interrupts | X | X(5) | - |
| All other interrupts | X | - | - |
Note:
- The I/O pin must be configured according to Asynchronous Sensing Pin Properties in the PORT section.
- For the peripheral to run in Standby sleep mode, the RUNSTDBY bit of the corresponding peripheral must be set.
- In Standby sleep mode, only the RTC functionality requires the RUNSTDBY bit to be set. In Power-Down sleep mode, only the PIT functionality is available.
- PTC is only available in devices with 8 KB Flash.
- 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.
