CPUFANOUT PWM Output Frequency Configuration Register - Index 02h
(Bank 0)
PWM_CLK_SEL2 (CPUFANOUT PWM Input Clock Source Select). This bit selects the
clock source for PWM output.
0: The clock source is 24 MHz.
1: The clock source is 180 KHz.
PWM_SCALE2 (CPUFANOUT PWM Pre-Scale Divider). The clock source for PWM
output is divided by this seven-bit value to calculate the actual PWM output frequency.
The maximum value of the divider is 127 (7Fh), and it should not be set to 0.
