General Description
These port pins also have selectable pullups when configured for input mode. The pullups are disengaged
when configured for output mode. The pullups are selectable on an individual port bit basis.
When the port pins are configured for special-function mode (SPI, TIM1, TIM2), pullups can be selectable
on an individual port pin basis.
1.5.12 Port E I/O Pins (PTE1/RxD–PTE0/TxD)
PTE1–PTE0 are special-function, bidirectional I/O port pins. These pins can also be programmed to be
serial communications interface (SCI) pins. See

Chapter 16 Input/Output Ports
Any unused inputs and I/O ports should be tied to an appropriate logic level

require termination, termination is recommended to reduce the possibility
of electro-static discharge damage.
