Description
Automatic Buffering Function ON/OFF Control
When this bit is to be set or cleared while CROM_EN =
0: Automatic buffering is OFF
1: Automatic buffering is ON
Buffering to Buffer RAM Control
This bit turns buffering in both automatic and manual
buffering modes on and off. In manual buffering mode,
set this bit after generation of the ISEC interrupt. This
bit is automatically reset when automatic buffering
stops.
0: Buffering is OFF
1: Buffering is ON
Buffering Control on Link Block Detection
0: Allocates area for seven sectors
1: Data are buffered, skipping the link block
Start-sector detection mode when the automatic
buffering function is in use
00: The header values for the previous and current
01: The header value detected in the current sector
10: A current sector with any header value is OK.
11: Start-sector detection is based on the interpolated
1, CBUF_EN should also be set or cleared
simultaneously. Otherwise, the validity of the status
indications in CBUFST0, CBUFST1 and CBUFST2
cannot be guaranteed.
