Features :
supports "long framing" and "short framing" (synchronous, frame-based protocol)
provides "master mode" and "slave mode"
build-in two 48x16 (or 24x32) data fifo to accelerate transmit/receive operation
programable data bits per one frame (sampling rate) : 1 ~ 256 bits/frame
programable data bits per word (resolution of each sampling) : 1 ~ 32 bits/word
programable multi-word (per frame) transfer : 1 ~ 16 words/frame
Related Pins :
- SDI
- SDO (output) : This pin contains the output data shifted to external audio/telephony codec devices
- SYNC (in/out) : This pin is the frame synchronization signal between SSI and codec devices. The SYNC may be
input or output depending on SSI operated in slave- or master-mode respectively.
- SCLK (in/out) : This pin is the serial bit clock between SSI and codec devices. Likewise, The SCLK may be
input or output depending on SSI operated in slave- or master-mode respectively.
(input) : This pin contains the input data shifted from external audio/telephony codec devices
Operation Modes :
- Master Mode : Once CFGH[2] is set to logic 1 and MD[25] is pull high, SSI is operated in master mode, and the
SYNC (determines the sampling rate) and SCLK is drived by SSI module to external codec devices.
SCLK frequence = EXTCLK/[2*(CFGL[8:15] + 1)]
SYNC period
=
SCLK * (CFGL[0:7] + 1)
(5.1.6a)
(5.1.6b)
- Slave Mode : Once CFGH[2] is set to logic 0 and MD[25] is pull down, SSI is operated in slave mode, the SCLK
and SYNC are drived externally (may be from codec devices). So the sampling rate and SCLK fre-
quence are determined by external devices, however software driver still need to properly set "serial
data bit length" (CFGH[8:10] ) as well as "data words per frame" ( CFGH[12:15] ) to make SSI
module working correctly.
- Loop mode : This mode (CFGH[1] =1) aims at selftesting. When this bit is set, serial data-out "SDO" is connected
to serial data-in "SDI" internally and SDO pin fixed at logic 0 state. Besides, if
Loop
and
Master
mode are chose concurrently, SSI module will not issue SYNC until TX-FIFO contains at least one
data word.
- Long Framing : When CFGH[3] is set to logic 1, SSI is operated in long framing mode. The following features
are
included in long framing mode :
consists of the following features.
- The SSI module always samples receive date (SDI) on the falling edge of SCLK, whereas always
pushes transmit data (SDO) on the rising edge of SCLK.
- The frame sync (SYNC) is asserted immediately as the first bit of transmit and receive data.
- The frame sync (SYNC) is asserted for one "serial word length" which determined by
CFGH[8:11].
Serial word length = CFGH[8:11] + 1
(5.1.6c)
- The frame sync rate (sampling rate) and SCLK frequence follow eq (5.1.6b) and (5.1.6a)
respectively on master mode and determined by external devices on slave mode.
- The transmit FIFO and receive FIFO is configued as 48x16 if "serial word length" <= 16,
and will be configured as 24x32 if "serial word length" > 16.
