Legacy-Free Keyboard/Embedded Controller with SPI and LPC Docking Interface
The PWM3 Clock Select 1 bit, D0 is used with the PWM3 Clock Multiplier bit, D1 and the PWM3 Clock
Select 0 bit, MBX98.7, and the Frequency Multiplier bits, MBXB3.0 and MBXB3.1, to determine the
PWM3 F
.
OUT

Frequency Multiply Register
The Frequency Multiply bits are used with PWM Clock Select 0 bit, PWM Clock Select 1 bit, and PWM
Clock Multiplier bit to select the frequency for PWM0, PWM1, PWM2, and PWM3. The PWM0, PWM1,
and PWM3 also have PWM standby clock bits.
See Table 18.1 and Table 18.2.
