STCR is an 8-bit readable/writable register that controls register access, the IIC operating mode
(when the on-chip IIC option is included), and on-chip flash memory control (in F-ZTAT
versions), and also selects the TCNT input clock. For details on functions not related to on-chip
flash memory, see section 3.2.4, Serial Timer Control Register (STCR), and descriptions of
individual 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.
Bit 7—Reserved: Do not write 1 to this bit.
Bits 6 to 4—I

C Control (IICX1, IICX0, IICE): When the on-chip IIC option is included, these
bits control the operation of the I

C bus interface. For details, see section 16, I
