Note: All registers are set to 0 when the LC74794/M is reset by the RST pin.
When 0, bytes for which error checking is
specified and that have no errors are written to
P-S. When 1, all bytes are written to P-S
regardless of errors.
The handling of bytes for which error checking
is turned off when error checking is enabled.
Error checking specification for bytes whose
