12.5

Serial Synchronous Controller (SSC)

• Provides serial synchronous communication links used in audio and telecom applications

(with CODECs in Master or Slave Modes, I2S, 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

12.6

Timer Counter (TC)

• Three 16-bit Timer Counter Channels

• Wide range of functions including:

– Frequency Measurement

– Event Counting

– Interval Measurement
