Chapter 1 Device Overview MC9S12XE-Family
1.2.3.76
PS0 is a general-purpose input or output pin. It can be configured as the receive pin RXD of serial
communication interface 0 (SCI0).
1.2.3.77
PT[7:6] are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC[7:6] of the enhanced capture timer (ECT).
1.2.3.78
PT[5] is a general-purpose input or output pin. It can be configured as input capture or output compare pin
IOC[5] of the enhanced capture timer (ECT) or can be configured to output the VREG_API signal.
1.2.3.79
PT[4:0] are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC[4:0] of the enhanced capture timer (ECT).
1.2.4
MC9S12XE-Family power and ground pins are described below.
Because fast signal transitions place high, short-duration current demands on the power supply, use bypass
capacitors with high-frequency characteristics and place them as close to the MCU as possible.
1.2.4.1
External power and ground for I/O drivers. Bypass requirements depend on how heavily the MCU pins are
loaded. All V
1.2.4.2
Input to the internal voltage regulator. The internal voltage regulator is turned off, if V
1.2.4.3
Power is supplied to the MCU core from the internal voltage regulator, whose load capacitor must be
connected to VDD. The voltage supply of nominally 1.8V is derived from the internal voltage regulator.
The return current path is through the VSS1,VSS2 and VSS3 pins. No static external loading of these pins
is permitted.
