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, 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.

Bits 7—Reserved: Do not set to 1.

Bits 6 to 4—I

C Control (IICX1, IICX0, IICE): These bits control the operation of the I

C bus

interface. For details, see section 16, I

C Bus Interface [H8S/2138 Group Option].
