40.4.11 SAI Receive Configuration 4 Register (I2Sx_RCR4)

This register must not be altered when RCSR[RE] is set.

This read-only field is reserved and always has the value 0.

FIFO Continue on Error

Configures when the SAI will continue receiving after a FIFO error has been detected.

On FIFO error, the SAI will continue from the start of the next frame after the FIFO error flag has been

On FIFO error, the SAI will continue from the same word that caused the FIFO error to set after the

FIFO warning flag has been cleared.

This read-only field is reserved and always has the value 0.

FIFO Packing Mode

Enables packing of 8-bit data or 16-bit data into each 32-bit FIFO word. If the word size is greater than 8-

bit or 16-bit then only the first 8-bit or 16-bits are stored to the FIFO. The first word in each frame always

starts with a new 32-bit FIFO word and the first bit shifted must be configured within the first packed word.

When FIFO packing is enabled, the FIFO read pointer will only increment when the full 32-bit FIFO word

has been read by software.

FIFO packing is disabled

8-bit FIFO packing is enabled

16-bit FIFO packing is enabled

This field is reserved.

This read-only field is reserved and always has the value 0.
