Key Features Of Pulse Width Modulation Timer - Samsung S5PC110 Manual

S5PC110_UM

1.2 KEY FEATURES OF PULSE WIDTH MODULATION TIMER

The Features supported by the PWM include:
• Five 32-bit Timers.
• Two 8-bit Clock Prescalers providing first level of division for the PCLK, and five Clock Dividers and
Multiplexers providing second level of division for the Prescaler clock and SCLK_PWM
Programmable Clock Select Logic for individual PWM Channels.
•
• Four Independent PWM Channels with Programmable Duty Control and Polarity.
• Static Configuration: PWM is stopped
• Dynamic Configuration: PWM is running.
• Auto-Reload and One-Shot Pulse Mode.
• One external input to start the PWM.
• Dead Zone Generator on two PWM Outputs.
• Level Interrupt Generation.
The PWM has two operation modes, namely, Auto-Reload and One-Shot Pulse:
• Auto-Reload Mode
In this mode, continuous PWM pulses are generated based on programmed duty cycle and polarity.
• One-Shot Pulse Mode
In this mode, only one PWM pulse is generated based on programmed duty cycle and polarity.
To control the functionality of PWM, 18 special function registers are provided. The PWM is a programmable
output, dual clock input AMBA slave module and connects to the Advanced Peripheral Bus (APB). These 18
special function registers within PWM are accessed via APB transactions.
