These bits select an input to OUT9.
0: The output of T4 DPLL 16E1/16T1 path. (default)
1: The output of T0 DPLL 16E1/16T1 path.
Refer to the description of the T4_INPUT_FAIL bit (b5, 73H).
This bit, together with the OUT9_EN bit (b6, 73H), determines whether clock is enabled to output on OUT9.
This bit determines whether the output on OUT5 is inverted.
0: Not inverted. (default)
1: Inverted.
This bit determines whether the output on OUT4 is inverted.
0: Not inverted. (default)
1: Inverted.
This bit determines whether the output on OUT3 is inverted.
