56F8033/56F8023 Data Sheet, Rev. 6
Freescale Semiconductor 99
6.3.19.5 Reserved—Bits 10–9
This bit field is reserved. Each bit must be set to 0.
6.3.19.6 Select Peripheral Input Source for PWM4/PWM5 Pair Source
(IPS0_PSRC2)—Bits 8–6
This field selects the alternate input source signal to feed PWM input PSRC2 as the PWM4/PWM5 pair
source.
• 000 = Reserved (default)
• 001 = TA3 (Internal) - Use Timer A3 output as PWM source
• 010 = ADC SAMPLE2 (Internal) - Use ADC SAMPLE2 result as PWM source
— If the ADC conversion result in SAMPLE2 is greater than the value programmed into the High Limit
register HLMT2, then PWM4 is set to 0 and PWM5 is set to 1
— If the ADC conversion result in SAMPLE2 is less than the value programmed into the Low Limit
register LLMT2, then PWM4 is set to 1 and PWM5 is set to 0
• 011 = CMPAO (Internal) - Use Comparator A output as PWM source
• 100 = CMPBO (Internal) - Use Comparator B output as PWM source
• 11x = Reserved
• 1x1 = Reserved
6.3.19.7 Select Peripheral Input Source for PWM2/PWM3 Pair Source
(IPS0_PSRC1)—Bits 5–3
This field selects the alternate input source signal to feed PWM input PSRC1 as the PWM2/PWM3 pair
source.
• 000 = I/O pin (External) - Use a PSRC1 input pin as PWM source (default)
• 001 = TA2 (Internal) - Use Timer A2 output as PWM source
• 010 = ADC SAMPLE1 (Internal) - Use ADC SAMPLE1 result as PWM source
— If the ADC conversion result in SAMPLE1 is greater than the value programmed into the High Limit
register HLMT1, then PWM2 is set to 0 and PWM3 is set to 1
— If the ADC conversion result in SAMPLE1 is less than the value programmed into the Low Limit
register LLMT1, then PWM2 is set to 1 and PWM3 is set to 0
• 011 = CMPAO (Internal) - Use Comparator A output as PWM source
• 100 = CMPBO (Internal) - Use Comparator B output as PWM source
• 11x = Reserved
• 1x1 = Reserved
