This was done in this rather poopy manner because when outputting -(and inputting) a sine wave, such as in the case of TDD, any repeated samples -(because of PCM bus contention) will result in nasty-sounding distortion. The -Mitel STPA chips (MT8920) have a contention mechanism, which results in a -situation where, if the processor accesses a timeslot that is currently -being transmitted or received, it will HOLD the bus until it is done with -the timeslot. This means that there can be cases where we are trying -to write to a timeslot, and its already outputting the same value -as the last one (since we didnt get there in time), and in a sine-wave -output, distortion will occur. In any other output, it will be utterly -un-noticeable. So, what we do is use a pattern that gives us the most -flexibility in how long our interrupt latency is (note: Even with this, -our interrupt latency must be between 4 and 28 microseconds!!!) Essentially -we receive the interrupt just after the 24th channel is read. It will -take us AT LEAST 30 microseconds to read it, but could take as much as -35 microseconds to read all the channels. In any case it's the very -first thing we do in the interrupt handler. Worst case (30 microseconds) -is that the MT8920 has only moved 7 channels. That's where the 6 comes from. -*/ - -static int chseq_t1[] = - { 6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,1,2,3,4,5 } ; - -static int chseq_e1[] = - { 6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,1,2,3,4,5 } ;
