14.1 Introduction
All MCUs in the MC9S08DZ128 Series include SCI1 and SCI2.
NOTE
MC9S08DZ128 Series devices operate at a higher voltage range (2.7 V to
5.5 V) and do not include stop1 mode. Please ignore references to stop1.
14.1.1 SCI2 Configuration Information
The SCI2 module pins, TxD2 and RxD2 can be repositioned under software control using SCI2PS in
SOPT1 as shown in Table 14-1. SCI2PS in SOPT1 selects which general-purpose I/O ports are associated
with the SCI2 operation.
