1.2.3.62
PS5 is a general-purpose input or output pin. It can be configured as master output (during master mode)
or slave input pin (during slave mode) MOSI of the serial peripheral interface 0 (SPI0).
1.2.3.63
PS4 is a general-purpose input or output pin. It can be configured as master input (during master mode) or
slave output pin (during slave mode) MOSI of the serial peripheral interface 0 (SPI0).
1.2.3.64
PS3 is a general-purpose input or output pin. It can be configured as the transmit pin TXD of serial
communication interface 1 (SCI1).
1.2.3.65
PS2 is a general-purpose input or output pin. It can be configured as the receive pin RXD of serial
communication interface 1 (SCI1).
1.2.3.66
PS1 is a general-purpose input or output pin. It can be configured as the transmit pin TXD of serial
communication interface 0 (SCI0).
1.2.3.67
PS0 is a general-purpose input or output pin. It can be configured as the receive pin RXD of serial
communication interface 0 (SCI0).
1.2.3.68
PT[7:0] are general-purpose input or output pins. They can be configured as input capture or output
compare pins IOC[7:0] of the enhanced capture timer (ECT).
1.2.4
MC9S12XDP512RMV2 power and ground pins are described below.
1.2.4.1
External power and ground for I/O drivers. 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. Bypass requirements depend on how heavily the MCU pins are
loaded.
