PIO Controller
Power Management
AT91SAM7A1
Each USART has three programmable I/O lines. These I/O lines are multiplexed with signals
(TXD, RXD, SCK) of the USART to optimize the use of available package pins. These lines
are controlled by the USART PIO controller.
The USART is provided with a power management block that optimizes power consumption.
