<h3>Description:</h3>
|
||
|
|
<p>Provides direct random access to both input and output fifos. The state of the FIFO is not distured by reading these locations (ie no POP will be done). FIFO0 is accessible from addresses 0x0 - 0x1C, and is used for data outuput from the IOM to external devices. These FIFO locations can be read and written directly.
|
||
|
|
FIFO locations 0x20 - 0x3C provide read only access to the input fifo. These FIFO locations cannot be directly written by the MCU, and are updated only by the internal hardware. Writes to the FIFO0 will take effect immediately. The currently FIFO pointers
|
||
|
|
in register FIFOLOC indicate the current offset into each FIFO0 for the read and write operations.
|
||
|
|
Access to the FIFOs can only be done in word increments; Byte access and writes are not supported.
|
||
|
|
For push and pop style access to FIFO0 can be done using the FIFOPOP and FIFOPUSH registers below.</p>

<h3>Description:</h3>
|
||
|
|
<p>Sets the threshold values for incoming and outgoing transactions. The threshold values are used to assert the interrupt if enabled, and also used during DMA to set the transfer size as a result of DMATHR trigger.
|
||
|
|
The WTHR is used to indicate when there are more than WTHR bytes of open fifo locations available in the outgoing FIFO (FIFO0). The intended use to invoke an interrupt or DMA transfer that will refill the FIFO with a byte count up to this value.
|
||
|
|
The RTHR is used to indicate when there are more than RTHR bytes in the incoming FIFO (FIFO1) and a data transfer of this size can be supported, either through direct POP of the FIFO, or through DMA.
|
||
|
|
The value of both RTHR and WTHR are also used to set the data transfer size of DMA operations if DMATHR trigger is enabled.</p>

<p>Will repeat the next command for CMDRPT number of times. If CMDRPT is set to 1, the next command will be done 2 times in series. A repeat count of up to 31 is possible. Each command will be done as a seperate command, but the data will
|
||
|
|
be treated as packed, and aligned to byte boundaries. This differs when executing seperate commands without the CMDRPT set, as the data for each transaction is word aligned and any unused byte locations will be filled with 0 for read operations, or
|
||
|
|
discarded for write operations. For repeated commands (CMDRPT is nonzero), the data is packed and no bytes will be filled or discarded until the final command is done.
|
||
|
|
The register value is decremented for each repeated command and at the end of the repeated command set, will be set to zero. If subsequent commands are to be repeated, this register must be written again.</p>

<h3>Description:</h3>
|

|
|
<p>Provides the high order bytes of 2 or 3 byte offset transactions of the current command. Usage of these bytes is dependant on the offsetcnt field in the CMD register. If the offsetcnt == 3, the data located at OFFSETHI[15:0] will first be transmitted,
|
||
|
|
followed by OFFSETHI[7:0], followed by OFFSETLO (in the CMD register) prior to sending or receiving any transaction data (if programed via TSIZE field in the CMD register).
|
||
|
|
The offset bytes are always transmitted MSB first for all modules.</p>

<h3>Description:</h3>

|
|
<p>Provides control on which event will trigger the DMA transfer after the DMA operation is setup and enabled. The trigger event will cause a number of bytes (depending on trigger event) to be
|
||
|
|
transferred via the DMA operation, and can be used to adjust the latency of data to/from the IOM module to/from the dma target. DMA transfers are broken into smaller transfers internally of up to
|
||
|
|
16 bytes each, and multiple trigger events can be used to complete the entire programmed DMA transfer.</p>

For P2M DMA operations, the trigger will assert when the read FIFO has (RTHR/4) words available in the read FIFO, and will transfer (RTHR/4) words to SRAM. This trigger will NOT assert when the transaction

completes and there are less than RTHR bytes left in the fifo, since the RTHR has not been reached. In this case, enabling the CMDCMP trigger will transfer the remaining data from the commmand. If the CMDCMP trigger is not enabled, the module will initiate a transfer when the amount of data in the FIFO is equal to or greater than the remaining data in the DMA. In cases where one DMA setup covers multiple commands, this will only occur at the end of the last transaction when the DMA is near complete.<br><br>
