Product Dependencies
I/O Lines
Power Manager (PM)
Interrupt
The pins used for interfacing the USART may be multiplexed with the PIO lines. The program-
mer must first program the PIO controller to assign the desired USART pins to their peripheral
function. If I/O lines of the USART are not used by the application, they can be used for other
purposes by the PIO Controller.
To prevent the TXD line from falling when the USART is disabled, the use of an internal pull up
is mandatory. If the hardware handshaking feature or Modem mode is used, the internal pull up
on TXD must also be enabled.
The USART is not continuously clocked. The programmer must first enable the USART Clock in
the Power Manager (PM) before using the USART. However, if the application does not require
USART operations, the USART clock can be stopped when not needed and be restarted later.
In this case, the USART will resume its operations where it left off.
Configuring the USART does not require the USART clock to be enabled.
The USART interrupt line is connected on one of the internal sources of the Advanced Interrupt
Controller. Using the USART interrupt requires the INTC to be programmed first. Note that it is
not recommended to use the USART interrupt line in edge sensitive mode.
