12.2.6
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 (in F-ZTAT versions), and
also selects the TCNT input clock.
For details on functions not related to the 8-bit timers, see section 3.2.4, Serial Timer Control
Register (STCR), and 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.
Bit 7—Reserved: Do not write 1 to this bit.
Bits 6 to 4—I
interface when the IIC option is included on-chip. See section 16.2.7, Serial Timer Control
Register (STCR), for details.
Bit 3—Flash Memory Control Register Enable (FLSHE): Controls CPU access to the flash
memory control registers, the power-down mode control registers, and the supporting module
control registers. See section 3.2.4, Serial Timer Control Register (STCR), for details.
Bit 2—Reserved: Do not write 1 to this bit.
Bits 1 and 0—Internal Clock Select 1 and 0 (ICKS1, ICKS0): These bits, together with bits
CKS2 to CKS0 in TCR, select the clock to be input to TCNT. For details, see section 12.2.4,
Timer Control Register.
