Figure 14. CS8413 Buffer Memory Write Sequence - MODE 2
Buffer Mode 2
In buffer mode 2, two 8-byte buffers are available
to independently buffer each channel of channel
status data. Both buffers are identical to the channel
status buffer in mode 1 and are written to simulta-
neously, with locations 08H to 0FH containing CS
data for channel A and locations 10H to 17H con-
taining CS data for channel B. Both CS buffers can
be monitored using FLAG1 and FLAG2 as de-
scribed in the BUFFER MODE 1 section.
