STCR is an 8-bit readable/writable register that controls the I
controls the SCI operating mode, and selects the TCNT clock source in the 8-bit timers. STCR is
initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 4—I

Bit 3—Slave Input Switch (STAC): Controls switching of host interface input pins. Settings of
this bit are valid only when the host interface is enabled (slave mode).

Bit 2—Multiprocessor Enable (MPE): Controls the operating mode of SCI0 and SCI1. For
details, see section 12, Serial Communication Interface.
Bits 1 and 0—Internal Clock Source Select 1 and 0 (ICKS1, ICSK0): Together with bits CKS2
to CKS0 in TCR, these bits select timer counter clock inputs. For details, see section 9, 8-Bit
Timers.
