Chip signal name

Module signal Description

I/O

name

I2S0_MCLK

â

Serial master clock output

I/O

I2S0_RX_BCLK

SRCK

Serial receive clock. SRCK can be used as an input or output.

I/O

â¢ In asynchronous mode the receiver uses this clock signal

and it is always continuous.

â¢ In synchronous mode, the STCK port is used instead for

clocking in data.

I2S0_RX_FS

I2S0_RXD

SRFS

SRXD

Serial receive frame Sync. The SRFS port can be used as an input

I/O

or output. The frame sync is used by the receiver to synchronize

the transfer of data. The frame sync signal can be one bit or one

word in length and can occur one bit before the transfer of data or

right at the transfer of data. If SRFS is configured as an input, the

external device should drive SRFS during the rising edge of STCK

or SRCK.

Serial receive data. The SRXD port is an input and is used to bring

I

serial data into the receive data shift register.
