Internal Oscillator 22.1184MHz/11.0592MHz select bit
5
FS1 0: Internal OSC frequency is 11.0592MHz.
1: Internal OSC frequency is 22.1184MHz.(default)
4 Reserved Reserved bit and must be kept high.
Select Crystal Frequency:
This bit is used to adjust the oscillation circuit to meet the external crystal
3
SCF ^frequency.
0: For external crystal frequency < 24MHz.
1: For external crystal frequency > 24MHz.
2 Reserved Reserved bit and must be kept high.
1 PWM_Even PWM Even channels driving mode select bit
1: The driving mode of even PWM pins is forced to Hi-Z mode all the time.
0: The driving mode of even PWM pins is controlled by output mode register
(PxMy).
This bit is latched to SFR PWMCON3.HZ_Even after all reset.
