Freescale Semiconductor 43
• Main oscillator pads (EXTAL, XTAL) are tristate.
• Nexus output pads (MDO[n], MCKO, EVTO, MSEO) are forced to output.
4.4 Voltage supply pins
Voltage supply pins are used to provide power to the device. Two dedicated pins are used for 1.2 V
regulator stabilization.
4.5 Pad types
In the device the following types of pads are available for system pins and functional port pins:
S = Slow

A decoupling capacitor must be placed between each of the three VDD_LV/VSS_LV supply pairs to ensure stable
voltage (see the recommended operating conditions in the device datasheet for details).

1. See the I/O pad electrical characteristics in the device datasheet for details.
2. All medium and fast pads are in slow configuration by default at reset and can be configured as fast or medium (see PCR.SRC
in Section 19.5.3.8, “Pad Configuration Registers (PCR0–PCR122)).
