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

2C Control (IICX1, IICX0, IICE): When the on-chip IIC option is included, these

bits control the operation of the I

2C bus interface. For details, see section 16, I2C Bus Interface

[H8S/2138 Group Option].
