24.4.2.1 Output Multiplexer
The output multiplexer shown in Figure 24-75 and Figure 24-77 connects the 32 GTC
output lines and the 64 LTC output lines with the I/O groups (5 × 8 = 40 output lines) and
the output groups (7 × 8 = 56 output lines).
Figure 24-77 Output Multiplexer of LTCA2
The output multiplexer contains Output Multiplexer Groups (OMGs) that connect the
Local Timer Cells with the input lines of the I/O groups and output groups. The LTCs are
grouped into eight LTC groups (LTCG[7:0]) with 8 cells each. In the same way, I/O
groups and output groups are grouped into 12 groups (five I/O groups and seven output
groups) with 8 lines each.
