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.
1.5.12 Port E I/O Pins (PTE5–PTE2, PTE1/RxD, and PTE0/TxD)
PTE5–PTE0 are general-purpose, bidirectional I/O port pins. PTE1 and PTE0 can also be programmed
to be enhanced serial communications interface (ESCI) pins. PTE5–PTE2 are only available on the
48-pin LQFP package. See Chapter 15 Enhanced Serial Communications Interface (ESCI) Module and
Chapter 13 Input/Output (I/O) Ports.
NOTE
Any unused inputs and I/O ports should be tied to an appropriate logic level
(either V_DD or V_SS). Although the I/O ports of the MC68HC908GZ16 do not
require termination, termination is recommended to reduce the possibility
of static damage.
