[Bit 3] TMD: Watch bit
Bit 3 specifies switching to the watch mode.
Writing at this bit is possible only in the submode (SCS = 0). 0 is always read when this bit is read. This
bit is cleared at an interrupt request or reset.
(b) System clock control register (SYCC)
[Bit 7] SCM: System clock monitor bit
Bit 7 checks whether the current system clock is the main clock or subclock.
[Bits 4 and 3] WT1 and WT0: Oscillation stabilization time select bits
Bits 4 and 3 select the oscillation stabilization wait time of the main clock.
If the main mode is specified by the system clock select bit (SCS), the mode switches to main mode
after the selected wait time has elapsed.
The initial value of this bit is determined by the mask option. Do not rewrite this bit during the oscillation
stabilization period nor rewrite it concurrently with switching from low speed to high speed.
The oscillation stabilization time of the main clock is generated by dividing down the frequency of the
main clock. Since the oscillation frequency is unstable immediately after oscillation starts, use the
above table.
[Bit 2] SCS: System clock select bit
Bit 2 selects the system clock mode.
