Modes of operation
The UART functions in the same way in all the normal modes.
It has the following low power modes:
• Wait mode
• Stop mode
47.1.2.1
Run mode
This is the normal mode of operation.
47.1.2.2
Wait mode
UART operation in the Wait mode depends on the state of the C1[UARTSWAI] field.
• If C1[UARTSWAI] is cleared, and the CPU is in Wait mode, the UART operates
normally.
• If C1[UARTSWAI] is set, and the CPU is in Wait mode, the UART clock generation
ceases and the UART module enters a power conservation state.
C1[UARTSWAI] does not initiate any power down or power up procedures for the
ISO-7816 smartcard interface.
