12.7

Pulse Width Modulation Controller (PWM)

• One Eight-channel (SAM3A and 144-pin SAM3X) or One Four-channel (100-pin SAM3X) 16-

bit PWM Controller, 16-bit counter per channel

• Common clock generator, providing Thirteen Different Clocks

– A Modulo n counter providing eleven clocks

– Two independent Linear Dividers working on modulo n counter outputs

– High Frequency Asynchronous clocking mode

• Independent channel programming

– Independent Enable Disable Commands

– Independent Clock Selection

– Independent Period and Duty Cycle, with Double Bufferization

– Programmable selection of the output waveform polarity

– Programmable center or left aligned output waveform

– Independent Output Override for each channel

– Independent complementary Outputs with 12-bit dead time generator for each

channel

– Independent Enable Disable Commands

– Independent Clock Selection

– Independent Period and Duty Cycle, with Double Bufferization

• Synchronous Channel mode

– Synchronous Channels share the same counter

– Mode to update the synchronous channels registers after a programmable number

of periods

• Interfaced with Peripheral DMA (PDC) or with the DMA Controller (DMAC) Channels to

Reduce Processor Overhead

• Two independent event lines which can send up to 4 triggers on ADC within a period

• Three programmable external (PWMFIx pins) and three internal (from ADC, PMC controller

and Timer 0) Fault Inputs providing an asynchronous protection of outputs without MCU

intervention

• Stepper motor control (2 Channels)

12.8

High Speed Multimedia Card Interface (HSMCI)

• Compatibility with MultiMedia Card Specification Version 4.3

• Compatibility with SD Memory Card Specification Version 2.0

• Compatibility with SDIO Specification Version V2.0

• Compatibility with CE-ATA Specification 1.1

• Cards clock rate up to Master Clock divided by 2

• Boot Operation Mode support

• High Speed mode support

• Embedded power management to slow down clock rate when not used

• Supports 2 Multiplexed Slot(s)
