Synchronous Serial Interface (SSI)
The ConnectCore for i.MX51 module provides up to three synchronous serial interfaces (SSI)
that allows communicating with a variety of serial devices as standard CODECs, audio CODECs
implementing the I
2
S standard and Intel AC97 standard.
SSI is typically used to transfer samples in a periodic manner. The SSI consists of independent
transmitter and receiver sections with independent clock generation and frame
synchronization.
The main features of the SSI interface are the following:
Independent (asynchronous) or shared (synchronous) transmit and receive sections
operating in Master or Slave mode
Normal mode operation using frame sync
Network mode operation allowing multiple devices to share the port with as many as
32 time slots
Two sets of four 15 x 32 bits Transmit and Receive FIFOs.
Programmable data interface mode such like I
2
S, LSB, MSB aligned
Programmable word length 8, 10, 12, 16, 18, 20, 22 or 24 bits
Program options for frame sync and clock generation
Programmable I
2
S modes (Master, Slave or Normal)
AC97 support
