3.6.2 Synchronous Serial Interface
The Synchronous Serial Interface is capable of handling the protocols I2S, Short
Frame Sync, Long Frame Sync and other Telecom protocols. Receiver and trans-
mitter do act independently. Due to multiplexing interdependencies, the SSC is only
available with the Transmitter clock signal TK used for both directions if the UART IF
is enabled. JTAG reset, signal /ATRST, is also not available, if the SSC signal RF,
Receiver Frame Sync is used.

3.6.3 Multi Channel PWM Controller
Each PWM channel can be programmed individually in regard to IO pin assignment
and PWM functionality. Therefore, PWM application designers can choose a proper
channel and pin for their application with the chance not to interfere with other ne-
cessary interfaces.
