Register 16617 and Register 16618 (0x40E9 and 0x40EA),
Nonmodulo
These registers set the boundary for the nonmodulo RAM space
used by the sound engine. An appropriate value is automatically
loaded to this register during initialization. It should not be
modified for any reason.
Register 16619 (0x40EB), Sound Engine Frame Rate
Bits[3:0], Sound Engine Frame Rate
These bits set the frequency of the frame start pulse, which is
delivered to the sound engine to begin processing on each audio
frame. It effectively determines the sample rate of audio in the
sound engine. This register should always be set to none at least
one frame prior to disabling Register 16630 (0x40F6), sound
engine run, Bit 0, sound engine run, to allow the sound engine
to finish processing the current frame before halting.
