16.7 Port E
16.7.1 Port E Data Register
MC68HC908GR8 — Rev 4.0
MOTOROLA
NOTE:
Function:
Alternate
Address:
Port E is a 2-bit special-function port that shares two of its pins with the
serial communications interface (SCI) module.
The port E data register contains a data latch for each of the two port E
pins.
PTE1 and PTE0 — Port E Data Bits
Data direction register E (DDRE) does not affect the data direction of
port E pins that are being used by the SCI module. However, the DDRE
bits always determine whether reading port E returns the states of the
latches or the states of the pins. See
RxD — SCI Receive Data Input

Freescale Semiconductor, Inc.
PTE1 and PTE0 are read/write, software programmable bits. Data
direction of each port E pin is under the control of the corresponding
bit in data direction register E.
The PTE1/RxD pin is the receive data input for the SCI module. When
the enable SCI bit, ENSCI, is clear, the SCI module is disabled, and
the PTE1/RxD pin is available for general-purpose I/O. See
Communications Interface
