| 31:0 | XMASK | R/W | 0h | Transmit data mask n enable bit. 0 Corresponding bit of transmit data (before
passing through reverse and rotate units)
is masked out and then padded with the
selected bit pad value (XPAD and XPBIT bits
in XFMT), which is transmitted out the
McASP in place of the original bit.
1 Corresponding bit of transmit data (before
passing through reverse and rotate units)
is transmitted out the McASP. |
