PULSE WIDTH MODULATION TIMER
2 FEATURES
The Features supported by the PWM include:
•
Five 32-bit Timers.
•
Two 8-bit Clock Prescalers providing first level of division for the PCLK, Five Clock Dividers and Multiplexers
providing second level of division for the Prescaler clock and one External Clock
•
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 Mode and One-Shot Pulse Mode.
•
One external input to start PWM.
•
Dead Zone Generator on two PWM Outputs.
•
Level Interrupt Generation.
The PWM has two operation modes:
•
Auto-Reload Mode
Continuous PWM pulses are generated based on programmed duty cycle and polarity.
•
One-Shot Pulse 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). The 18 special
function registers within PWM are accessed via APB transactions.
