PSC
The Programmable Serial Controllers (PSC) support different modes of operation (UART, Codec, AC97, SPI). UART is an
asynchronous interface, there is no AC characteristic.
3.3.20.1
Codec Mode (8,16,24 and 32-bit)/I2S Mode
NOTE
Output timing is specified at a nominal 50 pF load.
3 Inter Peripheral Clock is defined in the MPC5121e/MPC5123 Reference Manual
