Framing code
When set to 0, if there are no errors in bytes for
which error checking is turned on, those bytes are
written to P-S. When set to 1, all bytes are written
to P-S regardless of the error status.
Specifies handling of bytes for which error
checking is set to off but in which an error occurred
when error checking is turned on.
Error checking setting for unused data bytes.
Biphase (VPS), Hamming (PDC), and odd parity
(header).
Error check valid (Error checking can be turned on or off on a per-byte
basis.)
Error check invalid (Applications can select whether data for which an
error is detected is held or writing on a per-byte basis.)
Data write
(When the error bit is 0 in VPS mode.)
Error checking enabled for unused data bytes.
VPS: bytes 3, 4, and 6 to 10, PDCC (8/30/2): bytes 7 to 12, header 1:
bytes 14 to 37, header 2: bytes 14 to 29, header 3: bytes 14 to 21,
status 1 (3): bytes 7 to 25, status 2 (4): bytes 7 to 35
Error checking disabled for unused data bytes.
VPS: bytes 3, 4, and 6 to 10, PDCC (8/30/2): bytes 7 to 12, header 1:
bytes 14 to 37, header 2: bytes 14 to 29, header 3: bytes 14 to 21,
