29 / 160 page  Signal Pins 56F8335 Technical Data, Rev. 5 Freescale Semiconductor 29 Preliminary ISB0 (GPIOD10) 48 Schmitt Input Schmitt Input/ Output Input, pull-up enabled ISB0 - 2 — These three input current status pins are used for top/bottom pulse width correction in complementary channel operation for PWMB. Port D GPIO — These GPIO pins can be individually programmed as input or output pins. At reset, these pins default to ISB functionality. To deactivate the internal pull-up resistor, clear the appropriate bit of the GPIOD_PUR register. See Part 6.5.6 for details. ISB1 (GPIOD11) 50 ISB2 (GPIOD12) 51 FAULTB0 54 Schmitt Input Input, pull-up enabled FAULTB0 - 3 — These four fault input pins are used for disabling selected PWMB outputs in cases where fault conditions originate off-chip. To deactivate the internal pull-up resistor, set the PWMB bit in the SIM_PUDR register. See Part 6.5.6 for details. FAULTB1 55 FAULTB2 56 FAULTB3 57 ANA0 80 Input Analog Input ANA0 - 3 — Analog inputs to ADC A, channel 0 ANA1 81 ANA2 82 ANA3 83 ANA4 84 Input Analog Input ANA4 - 7 — Analog inputs to ADC A, channel 1 ANA5 85 ANA6 86 ANA7 87 VREFH 93 Input Analog Input VREFH — Analog Reference Voltage High. VREFH must be less than or equal to VDDA_ADC. VREFP 92 Input/ Output Analog Input/ Output VREFP, VREFMID & VREFN — Internal pins for voltage reference which are brought off-chip so that they can be bypassed. Connect to a 0.1 μF low ESR capacitor. VREFMID 91 VREFN 90 VREFLO 89 Input Analog Input VREFLO — Analog Reference Voltage Low. This should normally be connected to a low-noise VSSA.
