Note: The arbitration settings of a valid arbitration entry overrule the previously stored
arbitration settings for the next time mark. As a result, the use of more than one
valid arbitration entry between two time mark entries should be avoided.
MCYCLE [13:8] rw Mask for Cycle Comparison
This bit field determines the mask used to determine
the repetition rate for this arbitration entry.
This bit field is equivalent to the corresponding part
of the MOAMRn.AM bit field (see Page 22-108).
ARBM [25:24] rw Arbitration Mode
This bit field determines the action that is taken with
an arbitration window.
00
B
No action is taken; the status of the window is
not changed.
01
B
A merged (long) arbitration window will be
opened. If it is already opened, it is kept open.
10
B
A merged (long) transfer window will be
closed. Closing a merged transfer window
leads to a single (short) arbitration window
(transmission possible only during the transmit
enable window). The short arbitration window
is automatically closed after one time window.
11
B
A single (short) arbitration window
(transmission possible only during the transmit
enable window) is opened. A short arbitration
window is automatically closed after one time
window.
EC [31:28] rw Entry Code

B
defines this scheduler
memory entry as an arbitration entry.
0 [7:6],
[23:14],
[27:26]
r Reserved; read as 0; should be written with 0. Bits
are “don’t care” for scheduler operation when
EC = 0011
B
.
