|
* This module support maximum 2 pairs of tx/rx isochronous streams for |
|
* our convinience. |
|
* |
|
* In documents for ASICs called with a name of 'DICE': |
|
* - ASIC for DICE II: |
|
* - Maximum 2 tx and 4 rx are supported. |
|
* - A packet supports maximum 16 data channels. |
|
* - TCD2210/2210-E (so-called 'Dice Mini'): |
|
* - Maximum 2 tx and 2 rx are supported. |
|
* - A packet supports maximum 16 data channels. |
|
* - TCD2220/2220-E (so-called 'Dice Jr.') |
|
* - 2 tx and 2 rx are supported. |
|
* - A packet supports maximum 16 data channels. |
|
* - TCD3070-CH (so-called 'Dice III') |
|
* - Maximum 2 tx and 2 rx are supported. |
|
* - A packet supports maximum 32 data channels. |
|
* |
|
* For the above, MIDI conformant data channel is just on the first isochronous |
|
* stream. |
