PSC

The programmable serial controllers (PSC) support different modes of operation (UART, codec, AC97, SPI).

All the timing numbers specified for different PSC modes are design targets.

4.3.15.1

Codec Mode (8-, 16-, 24-, and 32-Bit) / I2S Mode

Table 39. Timing Specifications — 8-, 16-, 24-, and 32-Bit CODEC/I2S Master Mode1

NOTES:

1 Output timing is specified at a nominal 50 pF load.
