264 / 483 page  Peripherals Only one peripheral can be assigned to drive a particular GPIO pin at a time. Failing to do so may result in unpredictable behaviour. PWM signal PWM pin Direction Output value Comment OUT[n] As specified in PSEL.OUT[n] (n=0..3) Output 0 Idle state defined in GPIO- >OUT Table 51: Recommended GPIO configuration before starting PWM generation 6.12.5 Registers Base address Peripheral Instance Description Configuration 0x4001C000 PWM PWM0 Pulse-width modulation unit 0 Table 52: Instances Register Offset Description TASKS_STOP 0x004 Stops PWM pulse generation on all channels at the end of current PWM period, and stops sequence playback TASKS_SEQSTART[0] 0x008 Loads the first PWM value on all enabled channels from sequence 0, and starts playing that sequence at the rate defined in SEQ[0]REFRESH and/or DECODER.MODE. Causes PWM generation to start it was not running. TASKS_SEQSTART[1] 0x00C Loads the first PWM value on all enabled channels from sequence 1, and starts playing that sequence at the rate defined in SEQ[1]REFRESH and/or DECODER.MODE. Causes PWM generation to start it was not running. TASKS_NEXTSTEP 0x010 Steps by one value in the current sequence on all enabled channels if DECODER.MODE=NextStep. Does not cause PWM generation to start it was not running. EVENTS_STOPPED 0x104 Response to STOP task, emitted when PWM pulses are no longer generated EVENTS_SEQSTARTED[0]0x108 First PWM period started on sequence 0 EVENTS_SEQSTARTED[1]0x10C First PWM period started on sequence 1 EVENTS_SEQEND[0] 0x110 Emitted at end of every sequence 0, when last value from RAM has been applied to wave counter EVENTS_SEQEND[1] 0x114 Emitted at end of every sequence 1, when last value from RAM has been applied to wave counter EVENTS_PWMPERIODEND 0x118 Emitted at the end of each PWM period EVENTS_LOOPSDONE 0x11C Concatenated sequences have been played the amount of times defined in LOOP.CNT SHORTS 0x200 Shortcut register INTEN 0x300 Enable or disable interrupt INTENSET 0x304 Enable interrupt INTENCLR 0x308 Disable interrupt ENABLE 0x500 PWM module enable register MODE 0x504 Selects operating mode of the wave counter COUNTERTOP 0x508 Value up to which the pulse generator counter counts PRESCALER 0x50C Configuration for PWM_CLK DECODER 0x510 Configuration of the decoder LOOP 0x514 Amount of playback of a loop SEQ[0].PTR 0x520 Beginning address in Data RAM of this sequence SEQ[0].CNT 0x524 Amount of values (duty cycles) in this sequence SEQ[0].REFRESH 0x528 Amount of additional PWM periods between samples loaded into compare register SEQ[0].ENDDELAY 0x52C Time added after the sequence SEQ[1].PTR 0x540 Beginning address in Data RAM of this sequence SEQ[1].CNT 0x544 Amount of values (duty cycles) in this sequence SEQ[1].REFRESH 0x548 Amount of additional PWM periods between samples loaded into compare register 4430_161 v1.0 264 |
