Re: Regarding TPU emulation

Hi,

First, if the TPU is in emulation mode already, you don't download the
code again. You do it once, after reset.

I first initialize RAMBAR, then download the code.
(I guess you correctly decode the S19 file to binary words!!)
After it I initialize the whole TPU in the following order:
TPUMCRx (including emulation mode)
CIER
TICR
set up interrupt handler
CFSRx (you assign your new function #$F to the channel, I guess)
CPRx
channel parameters
and at last, via HSQRx I set a host request to the channels so that
channels initialize themselves.
