// In stereo mode, the two channels' caches are concatenated into one,

// and hold the interleaved frames.

// The cache holds 64 frames, so the upper half is not used in 8-bit mode.

// All registers mentioned below count in frames.

// The cache is a ring buffer; CCR_READADDRESS operates modulo 64.

// The cache is filled from (CCCA_CURRADDR - CCR_CACHEINVALIDSIZE)

// into (CCR_READADDRESS - CCR_CACHEINVALIDSIZE).

// All registers mentioned below count in frames. Shortcuts:

//   CA = CCCA_CURRADDR, CRA = CCR_READADDRESS,

//   CLA = CCR_CACHELOOPADDRHI:CLP_CACHELOOPADDR,

//   CIS = CCR_CACHEINVALIDSIZE, LIS = CCR_LOOPINVALSIZE,

//   CLF = CCR_CACHELOOPFLAG, LF = CCR_LOOPFLAG

// The cache is a ring buffer; CRA operates modulo 64.

// The cache is filled from (CA - CIS) into (CRA - CIS).

// The engine has a fetch threshold of 32 bytes, so it tries to keep

// CCR_CACHEINVALIDSIZE below 8 (16-bit stereo), 16 (16-bit mono,

// 8-bit stereo), or 32 (8-bit mono). The actual transfers are pretty

// unpredictable, especially if several voices are running.

// Frames are consumed at CCR_READADDRESS, which is incremented afterwards,

// along with CCCA_CURRADDR and CCR_CACHEINVALIDSIZE. This implies that the

// actual playback position always lags CCCA_CURRADDR by exactly 64 frames.

// CIS below 8 (16-bit stereo), 16 (16-bit mono, 8-bit stereo), or

// 32 (8-bit mono). The actual transfers are pretty unpredictable,

// especially if several voices are running.

// Frames are consumed at CRA, which is incremented afterwards,

// along with CA and CIS. This implies that the actual playback

// position always lags CA by exactly 64 frames.

// When CA reaches DSL_LOOPENDADDR, LF is set for one frame's time.

// LF's rising edge causes the current values of CA and CIS to be

// copied into CLA and LIS, resp., and CLF to be set.

// If CLF is set, the first LIS of the CIS frames are instead

// filled from (CLA - LIS), and CLF is subsequently reset.
