Table 2-2 to identify which pins can deactivate the internal pullup resistor.
Figure 6-8 SIM Pullup Disable Register (SIM_PUDR)
6.5.6.1 Reserved—Bit 15
This bit field is reserved or not implemented. It is read as 0 and cannot be modified by writing.
6.5.6.2 PWMA1—Bit 14
This bit controls the pullup resistors on the FAULTA3 pin.
6.5.6.3 CAN—Bit 13
This bit controls the pullup resistors on the CAN_RX pin.
6.5.6.4 EMI_MODE—Bit 12
This bit controls the pullup resistors on the EMI_MODE pin
Note: In this package, this input pin is double-bonded with the adjacent V
SS
pin and this bit should be
changed to a 1 in order to reduce power consumption.
6.5.6.5 RESET—Bit 11
This bit controls the pullup resistors on the RESET pin.
6.5.6.6 IRQ—Bit 10
This bit controls the pullup resistors on the IRQA and IRQB pins.
6.5.6.7 XBOOT—Bit 9
This bit controls the pullup resistors on the EXTBOOT pin.
Note: In this package, this input pin is double-bonded with the adjacent V
SS
pin and this bit should be
changed to a 1 in order to reduce power consumption.
6.5.6.8 PWMB—Bit 8
This bit controls the pullup resistors on the FAULTB0, FAULTB1, FAULTB2, and FAULTB3 pins.
6.5.6.9 PWMA0—Bit 7
This bit controls the pullup resistors on the FAULTA0, FAULTA1, and FAULTA2 pins.
