Address:73H
Type: Read / Write
Default Value: 01000000
Bit
Name
Description
7
OUT9_PATH_SEL
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.
6
OUT9_EN
Refer to the description of the T4_INPUT_FAIL bit (b5, 73H).
5
T4_INPUT_FAIL
This bit, together with the OUT9_EN bit (b6, 73H), determines whether clock is enabled to output on OUT9.
4OUT5_INV
This bit determines whether the output on OUT5 is inverted.
0: Not inverted. (default)
1: Inverted.
3OUT4_INV
This bit determines whether the output on OUT4 is inverted.
0: Not inverted. (default)
1: Inverted.
2OUT3_INV
This bit determines whether the output on OUT3 is inverted.
0: Not inverted. (default)
1: Inverted.
1OUT2_INV
This bit determines whether the output on OUT2 is inverted.
0: Not inverted. (default)
1: Inverted.
0OUT1_INV
This bit determines whether the output on OUT1 is inverted.
0: Not inverted. (default)
1: Inverted.

0
Output is enabled. (default)
1
Output is enabled when the T4 selected input clock does not fail.
Output is disabled (output low) when the T4 selected input clock fails.
(Whether the T4 selected input clock is switched or not, as long as the T4 selected
input clock does not change to be invalid, the T4 selected input clock does not fail).
