General Description
1.5.12 Port E I/O Pins (PTE5–PTE2 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 14 Enhanced Serial Communications Interface (ESCI) Module and
Chapter 12 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 MC68HC908GR16A do
not require termination, termination is recommended to reduce the
possibility of static damage.
