KB3930 Keyboard Controller Datasheet
Analog-to-Digital Converter (ADC)
6 ADC channels with 10-bit resolution.
All ADC pins can be alternatively configured as GPI (general purpose input)
function.
Pulse Width Modulator (PWM)
6 PWM channels are provided. (8-bit *2, 14-bit *2 and FANPWM(12-bit) *2)
Clock source selectable:.
1MHz/64KHz/4KHz/256Hz (for 8-bit PWM)
Peripheral clock or 1MHz (for 14-bit PWM)
Peripheral clock (for FANPWM)
Duty cycle programmable and cycle time up to 1 sec(for 8-bit PWM)
Watch Dog Timer (WDT)
32.768KHz input clock.
10-bit counter with 32ms unit for watchdog reset.
Three watchdog reset mechanisms.
Reset 8051 only
Reset whole chip, except GPIO module.
Reset whole chip including GPIO module.
Real Time Clock
32.768KHz input clock.
24-bit timer support.
General Purpose Timer (GPT)
Two 16-bit and two 8-bit general purpose timer with 32.768KHz clock source.
General Purpose Wakeup (GPWU)
Those I/O with GPI (general purpose input) configuration can generate
interrupts or wakeup events, except those pins named in GPXIOAxx.
