Chapter 14
Serial Communications Interface (S08SCIV4)
14.1 Introduction
All MCUs in the MC9S08DZ60 Series include SCI1 and SCI2.
NOTE
⢠MC9S08DZ60 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.
⢠The RxD1 pin does not contain a clamp diode to VDD and should not be
driven above VDD. The voltage measured on the internally pulled up
RxD1 pin may be as low as VDD â 0.7 V. The internal gates connected
to this pin are pulled all the way to VDD.
14.1.1 SCI2 Conï¬guration 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 SCI2 operation.
