Freescale Semiconductor 103
Figure 6-25 Internal Peripheral Source Select Register for PWM (SIM_IPS0)
6.3.21.1 Reserved—Bits 15–14
This bit field is reserved. Each bit must be set to 0.
6.3.21.2 Select Peripheral Input Source for FAULT2 (IPS0_FAULT2)—Bit 13
This field selects the alternate input source signal to feed PWM input FAULT2.
0 = I/O Pin (External) - Use PWM FAULT2 Input Pin (default)
1 = CMPBO (Internal) - Use Comparator B Output
6.3.21.3 Reserved—Bit 12
This bit field is reserved. It must be set to 0.
6.3.21.4 Select Input Source for FAULT1 (IPS0_FAULT1)—Bit 11
This field selects the alternate input source signal to feed PWM input FAULT1.
0 = I/O pin (External) - Use PWM FAULT2 Input Pin (default)
1 = CMPAO (Internal) - Use Comparator A Output
6.3.21.5 Reserved—Bits 10–9
This bit field is reserved. Each bit must be set to 0.
6.3.21.6 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
