– Generation of the Wakeup signal
Test Modes
– Remote Loopback, Local Loopback, Automatic Echo
Interfaced with Peripheral DMA (PDC) Channels to Reduce Processor Overhead (All
USARTs) and with the DMA Controller (DMAC) (USART0 and 1)
12.5
Serial Synchronous Controller (SSC)
Provides serial synchronous communication links used in audio and telecom applications
(with CODECs in Master or Slave Modes, I
2S, TDM Buses, Magnetic Card Reader,...)
Contains an independent receiver and transmitter and a common clock divider
Offers a configurable frame sync and data length
Receiver and transmitter can be programmed to start automatically or on detection of
different event on the frame sync signal
Receiver and transmitter include a data signal, a clock signal and a frame synchronization
signal
Interfaced with the DMA Controller (DMAC) to Reduce Processor Overhead
12.6
Timer Counter (TC)
Three 32-bit Timer Counter Channels
Wide range of functions including:
– Frequency Measurement
– Event Counting
– Interval Measurement
– Pulse Generation
–Delay Timing
– Pulse Width Modulation
– Up/down Capabilities
Each channel is user-configurable and can contain:
– Three external clock inputs
– Five internal clock inputs
– Two multi-purpose input/output signals
Two global registers that act on all three TC Channels
Quadrature decoder
– Advanced line filtering
– Position / revolution / speed
