interrupt is level sensitive and active low. As XIRQ is level sensitive, while this pin is low the MCU will
not enter STOP mode.

PF7 is a general-purpose input or output pin. It can be configured as the transmit pin TXD of serial
communication interface 3 (SCI3).
1.2.3.21
PF6 is a general-purpose input or output pin. It can be configured as the transmit pin RXD of serial
communication interface 3 (SCI3).
1.2.3.22
PF5 is a general-purpose input or output pin. It can be configured as the serial clock pin SCL of the IIC0
module.
1.2.3.23
PF4 is a general-purpose input or output pin. It can be configured as the serial data pin SDA of the IIC0
module.
1.2.3.24
PF[3:0] are a general-purpose input or output pins. They can be configured as chip select outputs [3:0].
1.2.3.25
PH7 is a general-purpose input or output pin. It can be configured as a keypad wakeup input. It can be
configured as slave select pin SS of the serial peripheral interface 2 (SPI2). It can be configured as the
transmit pin TXD of serial communication interface 5 (SCI5).
1.2.3.26
PH6 is a general-purpose input or output pin. It can be configured as a keypad wakeup input. It can be
configured as serial clock pin SCK of the serial peripheral interface 2 (SPI2). It can be configured as the
receive pin (RXD) of serial communication interface 5 (SCI5).
1.2.3.27
PH5 is a general-purpose input or output pin. It can be configured as a keypad wakeup input. It can be
configured as master output (during master mode) or slave input pin (during slave mode) MOSI of the
serial peripheral interface 2 (SPI2). It can be configured as the transmit pin TXD of serial communication
interface 4 (SCI4).
