16.4.2
Serial Pin Multiplexed Mode 1
(SMR0 Register [bits SM2, SM1, SM0] = [0 0 1])
This mode is “ COM1 snoop mode” with use of SCI_1 and internal registers.
DCD
,
RI
,
DSR
,
DTR
,
CTS
,
RTS
, RxDF and TxDF of SCIF are connected to COM1. RxD1 of SCI_1 is connected
to RxDF of SCIF internally and TxD1 of SCI_1 is unused.
So, COM2 is not available (N/A) and Rx of COM2 is fixed at 1. RxD3 and TxD3 of SCI_3 are
cross-connected to COM3.
The pin states of
DCD
,
RI
, and DSR of COM1 are reflected in bits DCD1, RI1, and DSR1 of the
SMR0 register. The pin state of
CTS
of COM1 is reflected in bit CTS1 of the SMR1 register.
Figure 16.2 illustrates the pin connection in serial pin multiplexed mode 1.
