FUNCTION
Reserved – A write to this location has no effect. A read returns 0s.
Buffer 3 watermark 1 This bit is set by hardware to indicate that the
number of quadlets in the associated buffer has risen above or fallen
below the value in DB3CFG3.WATERMARK1, depending on the
setting of DB3CFG0.WM1CTL.
Buffer 3 watermark 0 This bit is set by hardware to indicate that the
number of quadlets in the associated buffer has risen above or fallen
below the value in DB3CFG3.WATERMARK0, depending on the
setting of DB3CFG0.WM0CTL.
Buffer 3 logical cell available – When set to 1, a complete logical cell
has been confirmed into a transmit or receive buffer.
Buffer 3 full – When set to 1, indicates that there is no space available
in the current buffer. Software cannot write to this buffer when this bit is
set.
