The GPIO3, the GPIO4, the GPIO5, and the GPIO6

are configured as PWM LED drivers, which could

support up to 6mA current with programmable

frequency and duty cycle. Set PWMxEN[ ] bit to “1”

to enable PWM function of GPIOx.

PWM Frequence Selection

Each

LED

driver

may

be

independently

programmed to a different frequency by writing to

the GPIO’s FRE[2:0] register via the I2C serial

interface as shown in Table 6.

GPIOx/FRE[ ] PWM Frequency Setting

PWM Duty Cycle Selection

Each

LED

driver

may

be

independently

programmed to a different duty cycle by writing to

the GPIO’s DUTY[3:0] register via the I2C serial

interface as shown in Table 7.
