These bits are always read as 0. The write value should
always be 0.
Main Clock Oscillation Stop
0: The main clock oscillator and PLL remain active
1: The main clock oscillator and PLL are stopped during
Wakeup Clock Select
Selects the operating clock for use as the system clock
after the transition from the subclock operation in
software standby mode has been initiated by an
interrupt.
0: On leaving software standby mode, the main clock is

When the OSC32STP bit in TCR32K is 1, 1 cannot be
written to this bit. This bit is cleared to 0 when clearing
software standby mode while the value of WAKE32K
is 0. Dummy read of this bit must be performed twice
immediately after this bit is written to.
