Table 24-95 describes power-management features available for the UART.
For information about source clock gating and the sleep/wake-up transitions description, see Module Level Clock Management, Power, Reset, and Clock Management.
Feature | Registers | Description |
---|---|---|
Clock autogating | UART_SYSC[0] AUTOIDLE | This bit allows local power optimization in the module by gating the UARTi_ICLK clock on interface activity or gating the UARTi_FCLK clock on internal activity. |
Slave idle modes | UART_SYSC[4:3] IDLEMODE | Force-idle, no-idle, smart-idle, and smart-idle wakeup-capable modes are available. |
Clock activity | N/A | Feature not available |
Master standby modes | N/A | Feature not available |
Global wake-up enable | UART_SYSC[2] ENAWAKEUP | This bit enables the wake-up feature at module level. |
Wake-Up sources enable | N/A | Feature not available |
