Why only 32 instructions in the PIO peripherals

[/RaspberryPi]

They don't mention it much, but you only get 32 instructions of space shared between each of the 2 blocks of 4 pio state machines.
So you can write a program that is a max of 32 instructions long for a state machine, and no longer. And if you want more than 2 state machines with such a long but different programs, you can't do that. The 4 state machines in each batch share memory.
Is memory not dirt cheap these days? I was just wanting to make a low rpm (~200 RPM) brushless motor controller, and if I could put more instructions into the pio modules, they could make me the PWM waveform that goes to the transistors to end up a sine wave approximation. But you can't do math of course in the pio things, so as far as I can tell it's basically impossible, I could feed the PWM levels into the state machine using the buffer I guess, and it could do the timing. That helps slightly.
Basically I just want to bring this bizarre and unfortunate limitation up so hopefully they will improve it in the next revision.
