These bits select an input to OUT8.
0: The output of T4 DPLL 77.76 MHz path. (default)
1: The output of T0 DPLL 77.76 MHz path.
Refer to the description of the T4_INPUT_FAIL bit (b5, 72H).
This bit, together with the OUT8_EN bit (b6, 72H), determines whether a clock is enabled to be output on OUT8.
This bit determines the duty cycle of the output on OUT8.
0: 50:50. (default)
1: 5:8.
This bit determines the frequency of the output on OUT8.
0: 64 kHz + 8 kHz. (default)
1: 64 kHz + 8 kHz + 0.4 kHz.
This bit determines whether the output on OUT9 is inverted.
0: Not inverted. (default)
1: Inverted.
This bit determines whether the output on OUT7 is inverted.
0: Not inverted. (default)
1: Inverted.
This bit determines whether the output on OUT6 is inverted.
0: Not inverted. (default)
1: Inverted.
