Section 3 MCU Operating Modes
3.2.4
STCR is an 8-bit readable/writable register that controls register access, the IIC operating mode
(when the on-chip IIC option is included), an on-chip flash memory control (in F-ZTAT versions),
and also selects the TCNT input clock. For details of functions other than register access control,
see the descriptions of the relevant modules. If a module controlled by STCR is not used, do not
write 1 to the corresponding bit.
STCR is initialized to H'00 by a reset and in hardware standby mode.
Bits 7 to 5—I
port A and the operation of the I
details, see section 16.2.7, Serial/Timer Control Register (STCR).
Bit 4—I
and control registers (ICCR, ICSR, ICDR/SARX, and ICMR/SAR), the PWMX data registers and
control registers (DADRAH/DACR, DADRAL, DADRBH/DACNTH, and DADRBL/DACNTL),
and the SCI control registers (SMR, BRR, and SCMR).

Description
Addresses H'(FF)FF88 and H'(FF)FF89, and H'(FF)FF8E and H'(FF)FF8F, are used
for SCI1 control register access
Addresses H'(FF)FFA0 and H'(FF)FFA1, and H'(FF)FFA6 and H'(FF)FFA7, are used
for SCI2 control register access
Addresses H'(FF)FFD8 and H'(FF)FFD9, and H'(FF)FFDE and H'(FF)FFDF, are used
for SCI0 control register access
Addresses H'(FF)FF88 and H'(FF)FF89, and H'(FF)FF8E and H'(FF)FF8F, are used
for IIC1 data register and control register access
Addresses H'(FF)FFA0 and H'(FF)FFA1, and H'(FF)FFA6 and H'(FF)FFA7, are used
for PWMX data register and control register access
Addresses H'(FF)FFD8 and H'(FF)FFD9, and H'(FF)FFDE and H'(FF)FFDF, are used
for IIC0 data register and control register access
