Table 26
Description of the ‘rmod’ bits
Note
1.
rmod3 = bit 7 #, bit 6 #, bit 5 #, bit 4 #, bit 3 # C2P0 (where # is logic OR). This is non-zero for packet written CD-R.
rmod2 = bit 2 # C2P0 (where C2P0 is C2 flag for mode byte).
rmod1 = bit 1 # C2P0 (where C2P0 is C2 flag for mode byte).
rmod0 = bit 0 # C2P0 (where C2P0 is C2 flag for mode byte).
